With what sort of current do transformers only work with?
Alternating current
1 of 5
What is alternating current?
When the direction of the potential difference (also current) changes many times each second
2 of 5
How is magnetic field carried to the secondary coil?
The alternating current in primary coil creates a continuesly changing magnetic field and the iron core carries this magnetic field to the secondary coil
3 of 5
What does the changing magnetic field induce?
A changing potential difference in the secondary coil
4 of 5
How do you increase the magnetic field?
By increasing the number of coils
