Three resistors are connected as shown in the diagram,
Through the resistor 5 ohm , a current of 1 ampere is flowing .
a) what is the current flowing through the other two resistors ?
b) what is the potential difference across AB and across AC ?
c) What is the total resistance ?
answer with full steps and explanation !!

V= I R = 1 x 5 = 5 volt
a)
1 /Req = 1 / 10 + 1 /15
1/ req = 5 / 30
Req = 6
Now I = 5 / 6
I = 0.8 A
b ) potential difference across A and B
dv= (5 -0 )
dv = 5 volt
potential difference across A and C
dv = { 5 + ( 0.8 x 6 ) - 0 }
dv = 9.8 volt
r total = 5 + 6 = 11 Ω
