Does a step up transformer violate the principle of conservation of energy ?

Explanation

### Step-by-Step Solution:

1. **Understanding the Transformer**: A transformer consists of two coils of wire, known as the primary and secondary windings, wound around a magnetic core. In a step-up transformer, the secondary winding has more turns than the primary winding.

2. **Power in the Transformer**: The power input to the transformer (primary side) is given by the product of voltage (V) and current (I), which can be expressed as:
\[ P_{primary} = V \times I \]
