Competition Science Vision
(d) When a voltmeter is connected across two points to measure the potential
difference, it draws some current for its own deflection. This lowers the potential
difference to be measured. Thus the potential difference measured by a voltmeter
is ...

Voltmeter is a moving coil galvanometer having a high resistance connected in
series with its coil. By doing so resistance of voltmeter becomes very high. Hence
, it takes very small current from circuit when it is connected across the circuit to ...

If a moving coil ammeter and a moving coil voltmeter are used to measure / and V
, the result cannot be very accurate, even if the meters themselves are accurately
calibrated. This is because one or other of the meters is bound to register a ...
