Question

With generator convention, where the current leaves the positive terminal of the circuit element, if $\mathbf{P}$ is positive then positive real power is delivered.

(a) False

(b) True

Short answer

Answer

The correct option is (b).

Step-by-step solution

Define generator

A generator is a rotational electromagnetic device that converts mechanical energy into electrical energy.

Consider that the $P$ is the active power delivered by a generator, $V_{rms}$is a terminal voltage, $I_{rms}$ is the current generated, and $\theta$is the power angle. The relationship between these parameters is as follows:

$\mathbf{P}\mathbf{=}{\mathbf{V}}_{\mathbf{rms}}\mathbf{}{\mathbf{I}}_{\mathbf{rms}}\mathbf{}\mathbf{cos\theta }$

Use the definition of root mean square voltage

We know from the definition of a generator that, a generator generates positive real power. The current leaves the generator’s positive terminal.

Thus, Option (b) is correct.
