Question

How many resistors of resistance 176W are connected is parallel for the flow of the 2Ain220V supply

Answer 1

Answer:

Given : I=5A

V=220V

Req =

I

V

=

5

220

=44Ω

Now let n resistor of 176Ω each are connected in parallel

then Req =

n

R

=44

n=

44

176

=4

Hence 4 resistors are required

option (D) is correct.
