Explanation / Answer

Let's start with calcualting equivalent resistance of the circuit

Req= 5 + ( 10 x 10 )/ ( 20) = 10 ohms

I = V/R eq=10/ 10 = 1 A

a) Current through a = 1 A

b) V ( through a) = 5 V

c) Current through b = 0.5 A

d) Potential across b =5 V

e) Current btrough C = 0.5 A

f) V ( across C) = 2.5 V

g)I ( through D) = 0.5 A

h) V ( through c) = 2.5 V
