Reactance

Question 1

Capacitive Reactance:

Answer 1

Capacitive reactance is the opposition to the flow of AC caused by capacitors in a circuit.

Question 1

Reactance:

Answer 1

Reactance is a concept primarily associated with electrical circuits and alternating current (AC).
It represents the opposition that a circuit component offers to the flow of AC.

Question 2

Inductive Reactance

Answer 2

Inductive reactance is the opposition to the flow of AC caused by inductors in a circuit.

Question 3

Impedance (Z):

Answer 3

Impedance is the overall opposition that a circuit component (or a combination of components) offers to the flow of AC.

It combines both resistance and reactance.

Question 4

Phase Angle:

Answer 4

The phase angle represents the phase relationship between the voltage and current in an AC circuit with reactance.

Question 5

Positive Phase Angle:

Answer 5

Indicates a capacitive circuit.

Question 6

Negative Phase Angle:

Answer 6

Indicates an inductive circuit.

Question 7

Zero Phase Angle:

Answer 7

Indicates a purely resistive circuit

Question 8

Reactance in Series and Parallel:

Answer 8

In a series circuit, total reactance is the algebraic sum of individual reactances.

In a parallel circuit, the reciprocal of the total reactance is the sum of the reciprocals of individual reactances.
