Question

What is the current if 4 ohm and 2 ohm resistors are connected to 6 v potential difference is applied

Answer 1

Explanation:

equivalent resistance = 4+2=6 ohm

potential difference= 6 V

current, I = V/R = 6/6 = 1 A

Answer 2

Answer:

18/4A(parallel resistors),1A(series resistors)

Explanation:

when resistors in parallel V=IR

1/R=1/4+1/2=3/4

R=4/3

I=6*3/4==18/4A

when resistors are connected in series

V=IR

I=6/6=1A
