# Why voltage of a transformer secondary Falls If load is connected?

## Why voltage of a transformer secondary Falls If load is connected?

Loading the secondary winding with a simple load impedance causes a secondary current to flow, at any power factor, through the internal winding of the transformer. Thus voltage drops due to the windings internal resistance and its leakage reactance causes the output terminal voltage to change.

## What is common in two windings Transformere?

Series Connected Secondary Transformer As the two windings are connected in series, the same amount of current flows through each winding, then the secondary current is the same at 2.5 Amps.

The reason the full-load voltage is less than the no-load voltage is because when there is no load on the source, the voltage drop across its internal impedance is equal to zero.

How does the secondary voltage in a transformer develop when the primary windings are connected to a source voltage?

In a single-phase voltage transformer the primary is usually the side with the higher voltage. When an electric current passed through the primary winding, a magnetic field is developed which induces a voltage into the secondary winding as shown.

### Why is there voltage between neutral and ground?

this is because the ground is energized. but it could also be that voltage going through a light and trying to return to the electrical panel on the white, but not being able to get there due to an open neutral that is touching the bare metal of the can light or a ground wire.

### Why is voltage between neutral and earth?

Neutral-to-earth voltage (N-E), sometimes called “stray voltage,” is a condition that results when an electrical current flows through a neutral conductor. Stray voltage occurs when electricity “leaks” from the black wire directly to the white or ground wires before passing through the device to be powered.

How does an autotransformer differ from a two winding transformer?

In two winding transformer, whole power is transferred from primary to secondary side by means of induction ONLY While, in the case of Auto transformer, part of the whole power is transferred by induction and rest of the power is transferred through conduction.
