Question

find the value of R2, if total current in the circuit is 9A. given the value of r1 is 4 ohm?​

Answer 1

Explanation:

total resistance through circuit = 1/r1 +1/r2

= 1/4 + 1/ r2 = R2 + 4 / 4×R2

We know V= IR

V= 9 ( R2+4/ 4R2)

V= (9R2 + 36 ) 4R2

please give the value of p.d otherwise the answer cant be calculated completely
