Denim fabric was named after Nimes, France ( serge de Nimes - 'serge from Nimes'). The city gave denim its name. It's not a country, village, or mill name.

A voltmeter is specifically designed to measure electrical potential difference (voltage) between two points in a circuit. Galvanometer detects current, ammeter measures current, and ohmmeter measures resistance.

An ammeter is the instrument used to measure electric current flowing through a circuit. It is connected in series with the circuit element whose current is to be measured.

An ohmmeter measures electrical resistance. Ohm's law states that resistance equals voltage divided by current, and ohmmeters are designed to measure this property directly.

A galvanometer is an instrument that can detect AND measure electric current. Unlike an ammeter which only measures current, a galvanometer is more sensitive and can detect the presence and direction of current, making it the correct answer.
