What is the function of a galvonometer in a circuit
Answers
Answer:
It is used for detecting the direction of current flows in the circuit. ... The null point means the situation in which no current flows through the circuit. It is used for measuring the current. The voltage between any two points of the circuit is also determined through galvanometer.
A galvanometer works as an actuator, by producing a rotary deflection (of a "pointer"), in response to electric current flowing through a coil in a constant magnetic field. They were the first instruments used to detect and measure small amounts of electric currents. The electric current is the rate of charge flowing in a cross- section of the conducting element in a second and its measurement unit is—in SI—the ampere (symbol A). Instruments that measure voltages and currents are called voltmeters and ammeters, respectively.
