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

The ratio of the transformers primary and secondary windings with respect to each other produces either a step-up voltage transformer or a step-down voltage transformer with the ratio between the number of primary turns to the number of secondary turns being called the “turns ratio” or “transformer ratio”.

### What is the ratio of the secondary voltage to the primary voltage with the turn ratio in the winding Mcq?

Explanation: Since turns ratio is equal to 1:2 the transformer will give higher voltage at secondary with respect to the primary voltage, and current in secondary thus will be halved.

#### When the turns ratio of transformer is 20 and the secondary AC voltage is 12v The primary voltage is?

So, the correct answer is option C i.e. 240 V.

**What is secondary 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 do you calculate turns per transformer voltage?**

- Primary turns (n1) = Turns per volt(Tpv) * Primary voltage(V1)
- Secondary turns (n2) = Turns per volt(Tpv) * secondary voltage(V2) * 1.03 (Assume that there is 3% drop in transformer windings)
- The width of the tongue of laminations is approximately given by:-

## What is the phase relationship between the primary and secondary voltages 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.

The primary and the secondary terminal voltages of a transformer are proportional to the respective number of turns. The ratio of the primary to secondary terminal voltage is known as voltage ratio. The ratio of the primary to secondary turns is known as turns ratio of the transformer.

#### How to calculate the primary and secondary current of a transformer?

Transformer current calculations: Transformer turns ratio, V(primary) * I(Primary) = V(secondary) * I(secondary) The primary voltage is equal to the product of the secondary voltage and primary current divided by secondary current.

**What is the ratio between primary and secondary voltages?**

Since there is a ratio of 1 to 4 between the turns in the primary and secondary circuits, there must be a ratio of 1 to 4 between the primary and secondary voltage and a ratio of 4 to 1 between the primary and secondary current. As voltage is stepped up, the current is stepped down, keeping volts multiplied by amps constant.

**What is the ratio of primary to secondary turns?**

The ratio of the primary to secondary turns is known as turns ratio of the transformer. At no load, voltage and turns ratios are equal. The impedances of the transformer windings being small, even at full load, they are nearly equal.
