Question

Answer the given question​

Answer 1

answer

(i) total resistance 40ohm

(ii) total current 0.3 A

(iii)0.3 A

Answer 2

Explanation:

R1 + R2 = 30 + 10 = 40ohm(in series)

1/Rn = 1/40 + 1/40

Rn = 1/2

Total Resistance in R1 ,R1, R3 is 1/2

And R4 is also there

so, 1/2ohm + 20ohm = 41/2ohm

V = IR

12V = I*41/2

I = 24/41A
