In a transformer, if the primary coil has more turns than the secondary coil, what type of transformer is it? (2021)
Steps
Concepts
Step 1: Understand what a transformer is. A transformer is a device that changes the voltage of electricity.
Step 2: Identify the two coils in a transformer: the primary coil (input) and the secondary coil (output).
Step 3: Look at the number of turns (loops of wire) in each coil. The primary coil has more turns than the secondary coil.
Step 4: Know that if the primary coil has more turns, it reduces the voltage when electricity goes to the secondary coil.
Step 5: Conclude that this type of transformer is called a step-down transformer because it steps down the voltage.
