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
angle.
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
added algebraically.
5- The ______________ power in watts can be calculated as
I^2R
6-Calculate XL with L = 30mH and f = 1kHz ( I have Xl=2piFL
2*3.141592653*1kHz*30mH
=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.
