Question

How many 175 ohm resistor in parallel are reqiired to carry 5 ampere on a 220volte line?

Answer 1

Resistance required in the circuit, R = V/I = 220V/5A = 44 W, Resistance of each resistor, r = 176 W


If n resistors, each of resistance r, are connected in parallel to get the required resistance R, then R = r/n    or n  = r/R   = 176/44 = 4

$\bold\green{Your\:Answer:-}$

Let the total no. of resistors = x

Given,

I = 5 A

V = 220 V

According to Ohm’s law,

V = IR

R = V/ I = 220/5 = 44Ω

Now for x number of resistors of resistance 176 Ω, the equivalent resistance of the resistors connected in parallel is 44 Ω.

1/44 = 1/176 + 1/176 + 1/176 .....χ times

1/44 = x / 176

=> x = 176/ 44

=> x = 4

Therefore, 4 resistors of 176 Ω are required to draw the given amount of current.
