Question

answer this question pls​

Answer 1

Series resistance = (10 + 10 +10)ohm = 30ohm

Parallel resistance = 1/30 ohm + 1/10ohm = 4/30ohm

=30/4ohm

=7.5 ohm

we know that,

V=IR

3 V= I * 7.5 ohm

I = 2.5 A

Therefore current drawn is 2.5 Amperes

Answer 2

Answer: resistance of three resistors is series =30 ohm

now, 1/10 +1/30 = 1/R  or 40/300 = 1/R

or R = 30/4

also current I=V/R =(3/30)*4 = 4/10 =0.4 ampere
