Inductance and capacitance
A common inductor found in fluorescent light fixtures is a
Ballast
Total parallel capacitance
CT= C1+C2+C3
The apparent resistance to ac by a capacitor is called
Capacitive resistance
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 energy stored by a capacitor is called an
Electrostatic charge
Capacitance is measured in
Farads
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
Inductance is measured in
Henrys
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
The resistance provided by an inductor in an AC circuit is called
Inductive reactance
A coil that opposes any change in current flow is called an
Inductor
Total series inductance formula
LT= L1+L2+L3
Which is not an example of an electromagnetic device
Resistor
A time delay relay that uses an RC timing circuit is called an
Solid state time delay relay
Total series capacitive reactance formula
XCT= XC1+XC2+XC3
Total parallel inductive resistance
XLT=1/[(1/XL1)+(1/XL2)+(1/XL3)]
*The concept of a magnetic field being formed around a conductor when current flows through it is called:
electromagnetism
