Question

Calculate Total effective resistance​

Answer 1

Answer:

1. Total effective resistance of the circuit, R = R1 + R23 = 20 + 20 = 40.

2.Since 20 Ω is in series in the circuit, the current remains the same, i.e., 0.25 A.

Answer 2

Answer:

let 4Ω resistance be R1 nad 2Ω be R2 and 6Ω be R3.

Explanation:

now,

=R1+R2=4+2=6Ω=Rp   (connected in series.)

=Now Rp and R3 are connected in parallel.

∴1/6+1/6=2/6

∴Resultant resistance=6/2=3Ω

Ans=3Ω
