Voltage= 220V

Current = 5A

Resistance= 44ohm

Resistance of 44ohm is required

we know resistance in parallel

if we have same resistors is

R = R'/n

where n is number of resistor used

Here R'= 176ohm and R is 44 ohm

n= R'/R = 176/44= 4

Number of resistors used = 4

Answer 2

How many 176ohms resistors (in parallel) are required to carry 5A on a 220V line?

V = 220V

C = 5A

R = 44ohm

Resistance of 44ohm is required

we know resistance in parallel

if we have same resistors is

R = R'/n

where n is number of resistor used

Here R'= 176ohm and R is 44 ohm

n= R'/R

= 176 / 44

= 4 ...✔
