Electrical Measurements | MCQs

Explanation

The ammeter is used to indicate the amount of current flowing to and from the battery.

It measures the electric current in amperes to monitor battery usage and health.

Explanation

A wattmeter is an electrical instrument which is used to measure the electric power (in watts) of any electrical circuit.

**Additional Information**

Voltmeter – is used to measure the electric potential difference between two points,

Wavemeter – is used to measure the wavelength of a radio wave,

Viscometer – is used to measure the viscosity of the liquid.

Explanation

 Both Hay’s bridge and Maxwell’s inductance capacitance bridges are used to measure the inductance.

Hay’s bridge is used for the measurement of inductance of high Q coils

whereas Maxwell’s inductance capacitance bridge is used for the measurement of inductance of low Q coils.
