Answer 2

Answer:

5ohm and 20 ohm are connected in series.

so, total resistance,R1 = 20+5 = 25 ohm

also, 15 ohm and 10 ohm are connected in series.

so, total resistance,R2 = 15+10 = 25 ohm

Now , R1 and R2 are connected in parallel.

effective resistance R:

1/R = 1/R1 + 1/R2

= 1/25 + 1/25

= 2/25

so, R = 25/2 = 12.5 ohm

By ohms law, V= IR

25 = I × 12.5

I = 25/12.5 = 2 A

total current = 2A
