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.
