i.Find the total resistance, RT , and solve for the current, I, through the
voltage source.
ii.Find all of the unknown currents in the circuit.
iii.Verify Kirchhoff's current law (KCL) at node a.

Refer to the following circuit

You have 4 resistors in parallel across 270 volts.
1/Rt = 1/5600 + 1/3900 + 1/4300 + 1/2700

I1 = 270 / 5600
I2 = 270 / 3900
I3 = 270 / 4300
I4 = 270 / 2700
I5 = 0
I6 = 0

Add up the 4 numbers above and compare to It = 270/Rt
