Inductance and capacitance Test with Answers Rated A
A common inductor found in fluorescent light fixtures
is a - -Ballast In a power supply that converts an ac input to
generate a dc output, a capacitor is commonly used
to - -Filter the rectifiers pulsating dc output

The resistance provided by an inductor in an AC
circuit is called - -Inductive reactance A time delay relay that uses an RC timing circuit is
called an - -Solid state time delay relay
The energy stored by a capacitor is called an -
-Electrostatic charge Which is not an example of an electromagnetic
device - -Resistor
Total series inductance formula - -LT=
L1+L2+L3
A coil that opposes any change in current flow is
called an - -Inductor
Total parallel capacitance - -CT= C1+C2+C3
Affects a DC circuit only when the current is first
turned on, turned off, or when there is a change in
the load resistance - -Inductance
One of the effects a capacitor has in a DC circuit is
that it will - -Charge to a voltage equal to the
source voltage
The apparent resistance to ac by a capacitor is called
