Atransformer consisting of two coils wrapped around an iron core is connected to a generator and a resistor (resistor is connected to the secondary coil). there are 11 turns in the primary coil and 18 turns in the secondary coil. the peak voltage across the resistor is 67 v. what is the peak emf of the generator?

The peak emf of the generator is 40.94 V.

Explanation:

Given that,

Number of turns in primary coil= 11

Number of turns in secondary coil= 18

Peak voltage = 67 V

We nee to calculate the peak emf

Using relation of number of turns and emf

Where, N₁ = Number of turns in primary coil

N₂ = Number of turns in secondary coil

E₂ = emf across secondary coil

Put the value into the formula

Hence, The peak emf of the generator is 40.94 V.
