A 60 Hz, 220 kV AC voltage is applied to an
electric equipment which may be represented
by a resistance of 1.0 Ώ in series with an
inductive reactance of 5.67 Ώ. Calculate:
The instant of switch closure in the voltage
cycle for which the exponential component of
current will have:
1. its greatest positive value
2. its greatest negative value
3. zero value.
4.Assuming that the switch is closed at condition (1),
calculate: The AC and DC and total values of current at the instant 0.01 sec after
