BEE Circuit Analysis 3

Question 1

Norton's equivalent circuit consists of:

Accepted Answer

Current source in parallel with resistance

Answer

Norton equivalent: short-circuit current source (IN) in parallel with Norton resistance (RN).

Question 2

Superposition theorem applies to circuits that are:

Accepted Answer

Linear (containing only linear elements)

Answer

Superposition only works for linear circuits — the response is the sum of individual source responses.

Question 3

The power factor of a purely resistive circuit is:

Accepted Answer

1

Answer

In a purely resistive circuit, voltage and current are in phase, so power factor = cos(0°) = 1.

Question 4

A step-up transformer:

Accepted Answer

Increases voltage and decreases current

Answer

A step-up transformer increases voltage while proportionally decreasing current.

Question 5

The maximum power transfer theorem states maximum power is delivered when:

Accepted Answer

Load resistance equals source resistance

Answer

Maximum power transfer occurs when RL = RS (load matches source impedance).
