Question

if primary equivalent resistance is converted to secondary equivalent resistance then the primary resistance must be multiplied by​

Answer 1

Answer:

The equivalent circuit diagram of any device can be quite helpful in the pre-determination of the behavior of the device under the various condition of operation. It is simply the circuit representation of the equation describing the performance of the device.

E2/E1

The induced emf E1 is equal to the primary applied voltage V1 less primary voltage drop. This voltage causes current I0 no-load current in the primary winding of the transformer. The value of no-load current is very small, and thus, it is neglected.

Hence, I1 = I1’. The no-load current is further divided into two components called magnetizing current (Im) and working current (Iw).

These two components of no-load current are due to the current drawn by a non-inductive resistance R0 and pure reactance X0 having voltage E1 or (V1 – primary voltage drop).
