A loss free transformer has 500 turns on its primary winding and 2500 ...
Given data:
Primary winding turns (N1) = 500
Secondary winding turns (N2) = 2500
Secondary voltage (V2) = 200 V
Secondary current (I2) = 8 A

To find:
Primary voltage (V1) and primary current (I1)

We know that the transformer is loss-free, which means there is no power loss in the transformer. Therefore, we can use the formula for power in a transformer:

P1 = P2

Where P1 is the power in the primary winding and P2 is the power in the secondary winding.

Power is given by the product of voltage and current:

P = V * I

1. Calculating Power in Secondary Winding:
P2 = V2 * I2
= 200 V * 8 A
= 1600 VA

2. Calculating Power in Primary Winding:
P1 = P2
V1 * I1 = V2 * I2

3. Calculating Primary Voltage (V1):
V1 = (V2 * I2) / I1

4. Calculating Primary Current (I1):
I1 = (V2 * I2) / V1

Substituting the given values:
V1 = (200 V * 8 A) / I1
I1 = (200 V * 8 A) / V1

Since the transformer is loss-free, the power in the primary winding is equal to the power in the secondary winding. Therefore, we can equate the power equations:

V1 * I1 = V2 * I2

Simplifying the equation, we get:
V1 = V2 * (N1 / N2)
I1 = I2 * (N2 / N1)

5. Substituting the values and solving for V1:
V1 = 200 V * (500 / 2500)
= 40 V

6. Substituting the values and solving for I1:
I1 = 8 A * (2500 / 500)
= 40 A

Therefore, the primary voltage is 40 V and the primary current is 40 A. Hence, option B is the correct answer.
