Calculation of Primary and Secondary Current of a Transformer
Given:
Efficiency (η) = 80%
Power (P) = 4 kW
Primary Voltage (V1) = 100V
Secondary Voltage (V2) = 200V
Formula:
Efficiency (η) = (Output Power / Input Power) x 100%
Output Power (P2) = V2 x I2
Input Power (P1) = V1 x I1
Solution:
Output Power (P2) = V2 x I2 = 200V x I2
Input Power (P1) = V1 x I1 = 100V x I1
Efficiency (η) = (P2 / P1) x 100%
80% = (200V x I2) / (100V x I1) x 100%
80% = 2 x (I2 / I1) x 100%
I2 / I1 = 0.4
I1 = P1 / V1 = 4 kW / 100V = 40A
I2 = I1 x 0.4 = 40A x 0.4 = 16A
Answer:
Primary Current (I1) = 40A
Secondary Current (I2) = 16A
