| What is meant by Ideal transformer? |
The
transformer having:
1. It has no loss.
2. Its winding has zero resistance.
3. Leakage flux is zero
i.e. the flux produced by primary winding is linked with the secondary
winding.
4. Permeability of core is very high;
such that very small current is required to establish the flux in it.
5. For an ideal transformer the primary
applied voltage is same as primary induced emf ‘E1’ as there are no voltage
drop. Similarly the secondary induced emf ‘E2’ is also same as the terminal
voltage ‘E2’ is also voltage V2 across the load.
i.e. (E2/E1) = (V2/V1) =(N2/N1) = K

For an ideal
transformer there are no loss hence the product of I & V (Primary Voltage
V1 & Primary Current I1) is same as the product V2 & I2.
V1 I1 = input VA
V2 I2 = output VA
V1
I1 = V2 I2
(V2/V1) = (I1/I2) = K
