PHXII07:ALTERNATING CURRENT

356063 In case of \(AC\) circuits the relation \(V = iZ\), where \(Z\) is impedance, can directly applied to

1 Peak values of voltage and current only
2 Rms values of voltage and current only
3 Instantaneous values of voltage and current only
4 Both 1 and 2 are true
PHXII07:ALTERNATING CURRENT

356064 The AC voltage across a resistance can be measured using a:

1 Hot wire voltmeter
2 Moving coil galvanometer
3 Potential coil galvanometer
4 Moving magnet galvanometer
JEE - 2015
PHXII07:ALTERNATING CURRENT

356065 In an \(ac\) circuit the current

1 Is in phase with the voltage
2 Leads the voltage
3 Lags the voltage
4 Any of the above depending on the circumstances
PHXII07:ALTERNATING CURRENT

356066 Alternating current can not be measured by \(dc\) ammeter because

1 \(ac\) is virtual
2 \(ac\) cannot pass through \(dc\) ammeter
3 Average value of current is zero
4 \(ac\) changes its direction
