Multiple choice general knowledge

Why is impedance matching important?

  1. So the load will draw minimum power from the source

  2. To ensure that there is less resistance than reactance in the circuit

  3. To ensure that the resistance and reactance in the circuit are equal

  4. So the source can deliver maximum power to the load

D Correct answer
Explanation

Impedance matching ensures the source delivers maximum power to the load by minimizing reflections and power loss. When source and load impedances match, power transfer is optimized rather than minimized.
