How Many 440 ohm resistors (in parallel) are required to carry 5A on a 220 V line

Answers

Answered by kdevi8634

3

Answer:

Resistance = 440 ohm

I= 5A

V= 220 V

Firstly, we need to find the first resistance in the circuit

V= IR

220 V = 5A* R

R= 220V/5A

R= 44 ohm

No. of resistors required = 440ohm/44ohm

= 10 resistors

Hope it helps you ....
