A. 909.09 Amp
B. 90.90 Amp
C. 9.09 Amp
D. 9090.9 Amp

Ans. C​

Answer 1

For the single phase transformer

Find:- We have to find the primary full load current

Explanation:

Given-

Power=100 KVA

Voltage at primary=11000 V

Voltage at secondary=110 V

The primary full load current is,

we know the formula of Power

P=V×I

so, $I=\frac{V}{P}$

$I=\frac{100\times1000}{11000}$

Therefore the primary full load current is I=9.09 Amp

Answer 2

Correct option is ' C'
