Question

The primary of a transformer has 200 turns and the secondary has
1000 turns if the power output from the secondary at 1000V is 9kW,
calculate
a the primary voltage and
b the heat loss in the primary coil if the resistance of primary
is 0 2(ohm) if the efficiency of the transformer is 90%

Hi Mohit! Solution to your problem is as follows: (a)The relation between voltage drop in a coil, and number of turns in a coil is given as:

(b)The efficiency of the transformer is 90%

Input current=50A The resistance of the primary winding=0 2Ω Therefore, heat loss=I2R= (50A)2× 0 2Ω=500W Cheers!!

The primary of a transformer has 200 turns and the secondary has 1000 turns. if the power output from the secondary at 1000V is 9kW, calculate a. the primary voltage and b. the heat loss in the primary coil if the resistance of primary is 0.2(ohm) if the efficiency of the transformer is 90%
