The resistance is very very The resistance is very very high small 4 Deflecting torque is produced by current to be measured directly 7. Crompton Potentiometer Theory Series With CircuitĪlways connected in Parallel with the circuit. It is a Voltage measuring device which measures potential difference between the two points of a circuit. No Ammeter Voltmeter 1 It is a current measuring device which measures current through circuit. What is meant by vibration galvanometer Vibration galvanometer is a tuned detector and as such, it is very sensitive to Changes of frequency.ĭifferentiate between ammeter and voltmeter.
