Step-up and step-down transformers

19 Jul

Step Up Transformer
This type of transformer used for increase the output voltage. Number of turns in secondary coil is larger than the number of turns in primary coil.

Step Down Transformer
This type of transformer used for decrease output voltage. Number of turns in primary coil is larger than the number of turns in secondary coil

Transformer Equations
Vp is the potential, Ip is the current, Np is the turn on the primary coil and Vs is the potential, Is is the current, Ns is the turn on the secondary coil. We use following equations to find potential, current or number of turns of any coil;
N1/N2=V1/V2=I2/I1
