1- XC and the RC time constant are both measures of the
reaction of C to a change in ____?
2-The power factor is a numerical ratio with a value
between 0 and 1 equal to the ______________ of the phase
3-When V and I are out of phase because of reactance, the
product of V times I is called ______________ power
4-For _____________ inductors, the branch currents can be
5- The ______________ power in watts can be calculated as
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
and R = 10ohms. Calculate the inductance L.

what is moisture probe? What are there types? What is there
working principle and how they works?
guys this is one of technical question I had ask in
If you know its answer please let me know. The interviewers
were more interested in microwave moisture probe, so if you
find its any link please just forward me on my mail
Thanks in advance.

Practical condition in 400KV Sub station:- Breaker(open) , isolator(open), Earthing (close) at both end e.g A & B. Now Open A Stn Earthing than Open B stn Earthing (Which have a 50MVA reactor) , AND suddenly show R,Y,B phase 704KV,573KV,118KV respectively. Que is without closing of breaker how it is possible.????
