Equation of transformer?

The equation of a transformer can be represented as:

V1/V2 = N1/N2

Where:
V1 = primary voltage
V2 = secondary voltage
N1 = number of turns in the primary coil
N2 = number of turns in the secondary coil

This equation represents the relationship between the primary and secondary voltages and the number of turns in the coils of a transformer.

Transformer Equations

1. Voltage Ratio

```
N1 / N2 = V1 / V2
```

where:
- N1, N2 = Number of turns on primary and secondary windings
- V1, V2 = Voltage across primary and secondary windings

2. Current Ratio

```
I2 / I1 = N1 / N2
```

where:
- I1, I2 = Current through primary and secondary windings

3. Impedance Ratio

```
Z1 / Z2 = (N1 / N2)²
```

where:
- Z1, Z2 = Impedance of primary and secondary windings

4. Power Relationship

```
P1 = P2
```

where:
- P1, P2 = Power consumed by primary and secondary circuits (assuming no losses)

5. Turns Ratio and Coupling Coefficient

```
k = √(L12 / (L1 - L2)) = N1 / N2
```

where:
- k = Coupling coefficient
- L1, L2 = Inductance of primary and secondary windings
- L12 = Mutual inductance between primary and secondary windings

6. Leakage Inductance

```
L1L = L1 - L12
```

```
L2L = L2 - L12
```

where:
- L1L, L2L = Leakage inductance of primary and secondary windings
