The reading of ammeter and voltmeter in the following circuit are respectively

In the circuit shown in the figure, find: (a) the reactance of the circuit (b) impedance of the circuit (c )the current (d) readings of the ideal AC voltmeters(these are hot wire instruments and read rms values)

Find the reading of ammeter A and voltmeter V shown in the figure assuming the instruments to be ideal

In the circuit shown the reading of ammeter and voltmeter are 4 A and 20 V respectively. The meters are non ideal, then R ia

Assertion : In the circuit shown in figure ammeter and voltmeter are non-ideal. Why positions of ammeter and voltmeter are changed, reading of ammeter will increase while of voltmeter will decrease. Reason : Resistance of an ideal ammeter is zero while that of an ideal voltmeter is infinite.

In the, Ohm's law experiment ot find resistance of unknown resistor R, the arrangement is as shown. The resistance measured is given by R_("measured")=(V)/(i)V= voltage reading of voltmeter. i=current reading of ammeter. The ammeters and the voltmeter used are not ideal, and have resistance R_(A) and R_(V) respectively. For arrangement shown, the meausred resistance is
