Question

Please someone answer this.

Answer 1

Explanation:

total current = 2.1A

total resistance = 1/10+1/25

now , 5+2/50 = 7/50 = 50/7

total volt = 2.1 × 50/7 = 15v

current in 20 and 5 ohm will be

I = 15/25 =

l= 3/5 = 0.6A

now volt in 5 ohm resistance

is V = 5×0.6

= 3v

and current = 0.6A
