Question

what is the current if 12Ω and 4 Ω resistance are connected in parallel and 12 v potential difference is applied?​

Answer 1

Answer:

What is the current if 12 ohm and 4 ohm resistors are connected in parallel and 12 V potential difference is applied ? Current flowing through circuit is 4 Ampere 

Answer 2

Explanation:

given

potential difference= 12v

resistance-

R1 = 12ohm

R2= 4ohm

R1 and R2 are connected in parallel so equivalent resistance is

1/R = 1/R1+1/R2

1/R = 1/12+1/4

1/R = 1+3/12

1/R = 1/3

R = 3ohm

now current,

v = iR

12 = i×3

12/3 = i

4A = i
