### Step-by-Step Solution: 1. **Understanding Electric Sparks**: Electric sparks are a form of discharge that occurs when there is a sudden flow of electric current through the air or another medium. 2. **Role of Electric Field**: Sparks are produced when an electric field is applied. An electric field is created when there is a difference in electric potential (voltage) between two points. 3. **Breakdown Voltage**: Each material has a specific threshold known as the breakdown voltage or breakdown electric field. This is the point at which the electric field strength is strong enough to ionize the molecules in the air or the medium. ...
