An AC circuit current lags the voltage
consists only of a
pure inductance
and a power
source. The
relationship
between the
voltage and the
current in this
circuit is that the

,The power factor True ; apparent
of a load is equal
to the ____________
power divided by
the ____________
power.

A 10-ohms and 200
20-ohms resistor
are connected in
parallel. The total
line current
drawn by this
parallel
combination is 30
amps. Under
these conditions,
the line voltage
will be ____________
volts.

,A 20-ohm resistor 100
is connected in
series with a
parallel
combination of
two resistors, one
of which is 10-
ohms, the other
40-ohms. If the
voltage across
the parallel
combination is 40
volts, the voltage
across the 20-
ohm series
resistor is ________
volts.

, A certain 120- 12
volts single-
phase AC circuit
has a power
factor of 80
percent and a
watt-meter
reading of 1150
watts. The current
drawn by the
circuit is _________
amperes.

If the voltage 2400
between lines of
a 3-phase, 3-wire
delta connected
system is 2400
volts, then the
phase voltage is
_____________ volts
