Question

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 !!

Answer 1

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
