Question

A current of 4000 a is flowing at 220 vin the primary coil of transformer the voltage across the secondary is 10000v and 10per of power of power is lost what us the current thrufh secondary

Answer 1

Answer:

0.25A is answer

and plzz put brainleast

Explanation:

Current on primary (input) coil I

p

=5A

Voltage in primary coil V

p

=220V

Voltage in secondary coil V

s

=2200V

Output power is half of the input power i.e. P

s

=0.5P

p

∴ V

s

I

s

=0.5V

p

I

p

∴ 2200×I

s

=0.5×220×5

⟹ I

s

=0.25A
