AI Generated Solution

### Step-by-Step Solution **Step 1: Draw the Diagram of an AC Generator** - An AC generator consists of a rectangular coil (loop) of wire that is placed between the poles of a magnet (one north and one south). - The coil is mounted on a rotor that can rotate. - The ends of the coil are connected to slip rings, which are in contact with carbon brushes that allow the current to flow out of the generator. **Labelled Diagram:** ...
