A
They make electricity by moving a coil of wire in a magnetic field
2
Q
What is a transformer and what are the two different types
A
Step up and step down transformers, they are used to reduce energy loss by heat and change the electric flow. They are devices that increase or decrease the potential difference for example voltage of an alternating current
3
Q
What do step up transformers do to the voltage
A
Increase the voltage
4
Q
What do step down transformers do
A
Decrease the voltage
5
Q
What transformers are used closest to houses
