Answer 1

Explanation:

a. I = emf/ resistance

= 12 /4

= 3 A.

b. R1 and R2

I¹x 6 = I² x 3

I¹/I² = 1/2

as I = I¹ +I² = 3A

I¹ = 1/3 x 3 = 1A

I² = 2/3 x 3 = 2A

R3, 3A

R4, R5

I⁴x 2 = I⁵ x 2

I⁴/I⁵ = 1

I⁴ = 1/2 x 3 = 1.5A

I⁵ = 1/2 x 3 = 1.5 A

c. pd across AB is

I x R = 3 x 2 = 6V

pd across BC,

Í x R = 3 x 1 = 3V

pd across CD,

I X R = 3 x 1 = 3V
