Question

Consider Figure 3.5. the right. Match the following, those on the left to those on

$\left(i\right)\mathbf{}{\mathbf{I}}_{\mathbf{m}}$ (a) Exciting current
$\mathbf{\left(}\mathbf{ii}\mathbf{\right)}{\mathbf{I}}_{\mathbf{C}}$ (b) Magnetizing current

$\left(\mathrm{iii}\right){\mathbf{I}}_{\mathbf{e}}$ (c) Core loss current

Short answer

$\left(\mathrm{i}\right){\mathrm{I}}_{\mathrm{m}}$ (b) Magnetizing current

$\left(\mathrm{ii}\right){\mathrm{I}}_{\mathrm{C}}$ (c) Core loss current

$\left(\mathrm{iii}\right){\mathrm{I}}_{\mathrm{e}}$ (a) Exciting current

Step-by-step solution

Analise the circuit given in the figure 3.5.

Consider the circuit from the text book as:

The current that is required to energize the core of the transformer is known as the exciting current.

The current that is required to produce the flux in the core of the transformer is known as the magnetizing current.

The core loss current is establish due to magnetizing field as a result of alternating magnetization.

Match the symbol of the current with their names.

On the basis of the definition explain in the step 1, the correct match is,

$\left(\mathrm{i}\right){\mathrm{I}}_{\mathrm{m}}$ (b) Magnetizing current

$\left(\mathrm{ii}\right){\mathrm{I}}_{\mathrm{C}}$ (c) Core loss current

$\left(\mathrm{iii}\right){\mathrm{I}}_{\mathrm{e}}$ (a) Exciting current
