Question

To investigate the relation between the ratio of output and input voltage and no. Of turns in secondary and primary coil of self designed transformer

Answer 1

I have read and September to December I am not clear whether or have a great weekend to read from now until I am not sure I will also have read

Answer 2

The emf of the transformer in primary and secondary are directly proportional to each other.

• As the Es/Ep=Ns/Np
• The number of coil also depend upon the two types of the transformer one is the step up transformer in which.
• The secondary coils are 5 times more than the primary coil.
• In the step down transformer the primary coils are 5 time the secondary coil.
• This is how they change the emf of the transformer.
