The output voltage of an ideal transformer, connected to a 240 V a.c. mains is 24 V. when this transformer is used to light a bulb with rating 24 V, 24 W, calculate the current in the primary coil of the circuit.

Explanation

To solve the problem, we will follow these steps:

### Step 1: Understand the transformer relationship
An ideal transformer follows the relationship:
\[ \frac{V_p}{V_s} = \frac{N_p}{N_s} = \frac{I_s}{I_p} \]
where:
