Kirchhoff's Current Law Example No2

Find the currents flowing around the following circuit using Kirchhoff's Current Law.

 parallel and series

IT = Total current in the circuit

I1 current on path of R1

I2 current on path of R2

I3 current on path of R3

I1 = IT

I2 + I3 = I1

Total resistance in the circuit = 4 + 1(1/6 + 1/12)) = 4 + 4 = 8 Ohms

IT = 12/8 =
