A galvanometer when connected in a circuit, detects the presence of?

AResistance

BCurrent

CFrequency

DPotential difference

Answer:

B. Current

Read Explanation:

  • A galvanometer, when connected in a circuit, detects the presence of electric current.

  • galvanometer generates a rotary deflection of a pointer in response to electrical current flowing through a coil in a continuous magnetic field, acting as an actuator.

  • It is a device that detects weak electrical voltages and currents in a circuit.
