# What is a transformer that has its primary and secondary windings electrically and mechanically separated from each other?

## What is secondary winding of transformer?

A secondary winding is the winding of a transformer that receives its energy by electromagnetic induction from the primary winding. The secondary winding is facilitated with larger-gauge wire because of the increase in current, whereas the primary winding is made up of smaller-gauge wire due to less current conduction.

## How the primary and secondary of a transformer connected?

A current transformer has a primary coil of one or more turns of heavy wire. It is always connected in series in the circuit in which current is to be measured. The secondary coil is made up of many turns of fine wire, which must always be connected across the ammeter terminals.

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

In other words, i1/i2 = V2/V1. For example, if the current and voltage drop through the secondary coil is 3 amps and 10 volts, and the voltage drop through the primary coil is 5 volts, then the current through the primary coil is 10/5 * 3 = 6 amps. So the secondary has less voltage and more current.

## 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.
