What is the relationship between the output voltage and the number of turns on the primary coil?

The ratio of potential differences on the transformer coils matches the ratio of the numbers of turns on the coils. V p is the potential difference in the primary (input) coil in volts (V) V s is the potential difference in the secondary (output) coil in volts (V) n p is the number of turns on the primary coil.

Why the number of turns in primary and secondary coil are different?

Explanation: The number turns in the primary coil and secondary coil us never made equal to get different voltages on the requirements of work otherwise the transformer would not give any changes in voltages. Mostly the secondary coil has fewer turns than the primary coil.

What is the relation between the input and output voltages and the number of turns in the primary and the secondary coils?

The ratio between output voltage and input voltage is the same as the ratio of the number of turns between the two windings. A transformers output voltage is greater than the input voltage if the secondary winding has more turns of wire than the primary winding.

What is the relation between the number of turns and voltage of two winding transformer?

The voltage of the windings in a transformer is directly proportional to the number of turns on the coils. This relationship is expressed in below Equation. The ratio of primary voltage to secondary voltage is known as the voltage ratio (VR).

What will happen if the number of turns in primary and secondary coils are equal in a transformer?

If the turns ratio is equal to unity, that is n = 1, then both the primary and secondary have the same number of coil turns so therefore the voltages and currents will be the same for both the primary and secondary windings.

Why can the transformer be adjusted to have different numbers of turns on the secondary coil?

If you change the number of turns in the coils you change the induced emf. This allows you to change (transform) the voltage from the primary to the secondary coil. So if number of turns on the secondary coil is greater than on the primary coil, the output voltage will be greater than the input voltage.

What is the ratio of input and output power in primary and secondary windings of a transfer?

This ratio of 3:1 (3-to-1) simply means that there are three primary windings for every one secondary winding.

Why does more turns increase voltage?

From Faraday’s Law, we can deduce that the greater the rate at which the magnetic field changes, the greater the EMF induced. Also, the more turns there are on the secondary coil, the bigger the induced EMF. If we increase the turns on the secondary coil, the output voltage increases in proportion.

What is the ratio of the secondary voltage to the primary voltage with the turn ratio in the windings?

If the secondary output voltage is to be the same value as the input voltage on the primary winding, then the same number of coil turns must be wound onto the secondary core as there are on the primary core giving an even turns ratio of 1:1 (1-to-1).
