Question

A resister has resistance of 176 ohm . How many of these resister should be connected in parallel show that there combination draws a current of 5 ampere from 220volt supplies

Answer 1

it's very easy question it's question doing means wasting of time so I can't do this question please like my also answer

Answer 2

Answer:

From Ohms law

V=IR

220=5*R

R=44 Ohm

We know that

For // connection we have

1/R(total) =1/R1 +1/R2.........1/Rn

SO,

Let the no. Of registers be x

1/44=x/176

X=4
