6-Calculate XL with L = 30mH and f = 1kHz ( I have Xl=2piFL
=188 ohms Please check)
7-A parallel RL circuit has the values, R = 5kohms, XL =
5kohms. A voltage source of Vt = 10Vrms is connected in
parallel to R and L. Determine the total current, It
delivered by the voltage source Vt.
8-A series RC circuit has R = 1Mohm and C = 1microF. How
long would it take for the capacitor to fully discharge if
it is initially fully charged?
9-A circuit has real power = 300W and an apparent power of
500VA. Determine the power factor and phase angle.
10-The time constant for an LR series circuit is T = 0.1s

How many kinds of E.L.C.B and how to work E.L.C.B
where this neutral connection goes after returning from the
load(home ,factory,industries).Is it grounded at the
transformer side or atthe generator side .If it is grounded
then we also ground the earth connection.is there any
problem with this.
