Question

find the value of current(I) in the circuit give below:
​

Answer 1

Answer:

I=V÷R

V= 3v

R=20

=3÷20

=0.15 ampere

Answer 2

Answer:

your answer is 0.1 A

Explanation:

20ohm 20 ohm connected in parallel

effective resistance = (20× 20) /(20+20)

= 400/40

= 10ohm

20oh and 10ohm in series

effective resistance = 20+10

= 30ohm

from ohms law V= IR

I =V/R

I = 3/30

I = 1/10 = 0.1 A
