## What is the phase relationship between the primary and secondary voltage of a transformer?

What is the phase relationship between the primary and secondary voltages of a transformer? The primary and secondary voltages of a transformer are **180° out of phase**.

## What is the phase difference between primary and secondary emf?

The phase difference between transformer primary and secondary side voltages for each phase is **-25 degre**.

## What is the phase difference between secondary current and primary additional current?

This would imply that if the secondary is open circuit, the voltage differences between primary and secondary are **90 degrees out** of phase.

## What is the phase relationship between the core flux the magnetizing current and the induced EMFS in the primary and secondary winding of a transformer?

The function of the magnetizing component is to produce the magnetizing flux, and thus, it will be in phase with the flux. Induced emf in the primary and the secondary winding **lags the flux ϕ by 90 degrees**.

## How do you find the primary and secondary voltage of a transformer?

Solve the equation **Vs/Vp = Ns/Np** where Vs is the secondary voltage, Vp is the primary voltage, Ns is the number of secondary windings and Np is the number of primary windings. Divide the number of secondary windings by the number of primary windings, and multiply the source voltage by this ratio.

## What is the relationship effect of current and transformer windings quizlet?

**The current causes a magnetic field to be set up around both the primary and the secondary windings**. The moving flux causes a voltage to be induced into the secondary winding, countering the effects of the counter emf in the primary.
