AC Theory T3

for an inductor frequency is .......... to inductive reactance

what opposes current in an inductive circuit

• inductance

• resistance

• inductive reactance

• capacitive reactance

what component do we add to a circuit to improve power factor

what electrical equipment contains an inductor

• fluorescent light

• heating element

• transformer

• incandescent lamp

capacitive reactance is inversely proportional to

• resistance

• current

• voltage

• frequendy

inductance is measured in

• ohms

• henry

• farad

• watts

current through a resistor produces

• light

• heat

• resistance

• voltage

draw a phasor diagram for a series circuit that shows v1 across a resistor, v2 across a second resister

Answer explanation

both v1 and v2 should be on your reference line. voltage across a resistor is in pahse and can be found using the sum of the two values
