Transformers•Used to increase or decrease the voltage of alternating currents.
Transformers
Consist of 2 coils of wire. Primary Coil
Alternating current enters Secondary Coil
Alternating current leaves
It’s the difference in the number of turns of wire on each coil that causes the voltage the change.
2 Types of Transformers Step-up Transformer
Increase voltage Secondary more turns than
primary
Step-down Transformer Decrease voltage Primary more turns than
secondary
Math of a Transformer:
A step-up transformer has 400 turns on its primary coil and 600 turns on its secondary coil. If the primary coil is supplied with 120 V of alternating current, what will be the secondary (output) voltage?
ns= 600 turns np= 400 turnsVs= ?Vp= 120
