Multiple choice physics some natural phenomena safety from lightning lightning safety advanced of lightning

Why is a car or a bus safe place during lightening?

  1. Because it does not rain inside the bus.

  2. Because lightening cannot travel through the glass.

  3. Because a car or a bus is insulated from the Earth.

  4. None of the above.
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

A car or a bus stand on rubber tyres. Rubber being an insulator, the body of car / bus stays separated or insulated from the Earth. So, it does not attract lightening. If we take shelter in a car / bus during lightening, there is no chance to be hit by the lightening.

Multiple choice physics when current flows precaution with the electrical circuit precautions to be taken while dealing with current electrical safety devices used to protect from shock of electric current

Which of the following are correct safety precautions to be taken while using electricity?

  1. Don't yank an electrical cord from the wall.

  2. Fly your kite far away from power lines or substations.

  3. Do look up and look out for power lines before you climb a tree.

  4. All of these
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
Some precaution to be taken while using electricity:
1. DON'T plug a bunch of stuff into one outlet or extension cord.
It could damage the electrical system in your house or even cause a fire.
2. DO ask grown-ups to put safety caps on all unused electrical outlets.
Covering outlets will also help save energy by stopping cold drafts.
3. DON’T yank an electrical cord from the wall.
Pulling on a cord can damage the appliance, the plug or the outlet.
4. DO make sure all electric cords are tucked away, neat and tidy.
Pets might chew on electrical cords, and people might trip and fall.
5. DON'T ever climb the fence around an electrical substation.
If a ball or pet gets inside the fence, ask a grown-up to call the electric company - they'll come and get it out for you.
6. DO look up and look out for power lines before you climb a tree.
The electricity can go right through the tree branch - and right through you!
7. DON’T fly a kite near power lines.
The kite and the string may conduct electricity – sending it right through you to the ground.

Multiple choice physics when current flows precaution with the electrical circuit precautions to be taken while dealing with current electrical safety devices used to protect from shock of electric current

Which of the following are safety precautions to be taken while using electricity. Select correct option

  1. Avoid water at all times when working with electricity

  2. Never use equipment with frayed cords, damaged insulation or broken plugs

  3. Always use insulated tools while working.

  4. All of these
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

water can damage the circuits. it can also create a short circuit which may result into serious accidents. If insulation is damaged, then our body may come into direct contact with the electric current, resulting in an electric shock. Insulation is thus compulsory while working with electricity.

Which of the following are safety precaution to be taken while using electricity. Mark correct answer

  1. Know the wire code of your country.

  2. Always check all your GFCIs once a month

  3. Always use a circuit breaker or fuse with the appropriate current rating

  4. All of these
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Some precaution to be taken while using electricity:

  1. Know the wire code of your country.
  2. Always check all your GFCI’s once a month. A GFCI (Ground Fault Circuit Interrupter) is a RCD (Residual Current Device). They have become very common in modern homes, especially damp areas like the bathroom and kitchen, as they help avoid electrical shock hazards. It is designed to disconnect quickly enough to avoid any injury caused by over current or short circuit faults.
  3. Always use a circuit breaker or fuse with the appropriate current rating.

Multiple choice physics when current flows precaution with the electrical circuit precautions to be taken while dealing with current electrical safety devices used to protect from shock of electric current

Below are some safety precautions to be taken while using electricity. Select most appropriate option.

  1. Working outside with underground cabling can be dangerous

  2. Always put a cap on the hot/live wire while working on an electric board or service panel

  3. Take care while removing a capacitor from a circuit

  4. All of these
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Some safety precautions to be taken while using electricity:

  1. Try putting a cap on the live wire while working on circuit panels. The cap acts as an insulation and help in preventing any electric shock.
  2. We should be always careful when removing a capacitor from a circuit.
  3. Working outside with underground cabling can be dangerous. So we should be careful when working with underground cable.

Multiple choice physics when current flows precaution with the electrical circuit precautions to be taken while dealing with current electrical safety devices used to protect from shock of electric current

Which of the following is to be used as safety precaution while using electricity.

  1. Drain capacitors before working near them and keep the short circuit on the terminals during the work to prevent electrical shock.

  2. Never touch another persons equipment or electrical control devices unless instructed to do so.

  3. Enclose all electric contacts and conductors so that no one can accidentally come into contact with them.

  4. All of these
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Safety precaution while using electricity:

  1. Drain capacitors before working near them and keep the short circuit on the terminals during the work to prevent electrical shock. 
  2. Never touch another person’s equipment or electrical control devices unless instructed to do so. Don’t be too smart. Don’t try your luck. 
  3. Enclose all electric contacts and conductors so that no one can accidentally come into contact with them. If applicable do it always, if not be very careful.

Multiple choice physics when current flows precaution with the electrical circuit precautions to be taken while dealing with current electrical safety devices used to protect from shock of electric current

Which of the following are safety precaution to be taken while using electricity. Select correct answer.

  1. Always use appropriate insulated rubber gloves and goggles while working on any branch circuit or any other electrical circuit.

  2. Never try repairing energized equipment

  3. Never use an aluminium or steel ladder if you are working on any receptacle at height in your home

  4. All of these
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The safety precaution to be taken while using electricity:

  1. Always use appropriate insulated rubber gloves and goggles while working on any branch circuit or any other electrical circuit.
  2. Never try repairing energized equipment. Always check that it is de-energized first by using a tester. When an electric tester touches a live or hot wire, the bulb inside the tester lights up showing that an electrical current is flowing through the respective wire. Check all the wires, the outer metallic covering of the service panel and any other hanging wires with an electrical tester before proceeding with your work.
  3. Never use an aluminium or steel ladder if you are working on any receptacle at height in your home. An electrical surge will ground you and the whole electric current will pass through your body. Use a bamboo, wooden or a fiberglass ladder instead.
