Define transformer ans transformation ratio. |
|
Answer» Transformer—It is a device which is used to convert law alternating voltage at higher current into high alternating voltage at lower current and vice-versa. It works on the principle of mutual induction. Transformation ratio—It is ratio of number of turns in secondary coil (NS ) and number of turns in primary coil (NP). K = Ns/Np where, k is transformation ratio. |
