What is it mad up of?
2 coils of wire wounded into an iron core
2 of 6
What process makes the voltage in one coil induces a voltage in the second coil?
Electromagnetic induction
3 of 6
What is the formula for electrical power?
Electrical power=Current x Potential difference
4 of 6
When is the power in the secondary coil equal to the power of the primary coil?
When the transformer is 100% efficient
5 of 6
