( 
V = 2.78 V, 
A = 0.278 A)
Sol. The circuit shown above is a parallel circuit, and consists of a single node By assuming voltage V at the node, we can find out the current in 10 Ω Ω branch.
According to Kinrchhoff’s Current Law,
I 1 + I 2 + I 3 + I 4 + 5 = 10
By using Ohm’s law, we have
I 1 = 
= 
= 
= 
+ 
+ 
+ V + 5 = 10
V 
= 5
V [0.2 + 0.1 + 0.5 + 1] = 5
V = 
= 2.78 V Ans
The voltage across 10 Ω Ω resistor is 2.78 V
and the current passing through it is
I 2 = 
= 0.278 A Ans
