# Circuit analysis using source transformation?

Use source transformation to find I in the following circuit

combine the two voltage sources and two resistors to get below.

Then use thevenin equivalent to change current source and 2 Ω resistor to a voltage source of 4 volts and series R of 2 Ω.  (corrected)

Now just ohms law I = 6/16 = 3/8 amp = 0.375 amps

By source transformation the 2A source in parallel with the 2Ω can be replaced by it's Thevenin equivalent which is 2A*2Ω = 4V in series with a 2Ω resistance. The + side of the 4V source on the right. Then perform KVL assuming a clockwise current i:

8 - 6*i - 2*i + 4 - 8*i - 6 = 0

6 = 16*i and i = 3/8 A  =  375mA <<<<

The voltage sources reduce to 2V.

The series resistors reduce to 8+6=14Ω.

The I R reduces to 4v in series with 2Ω.

The whole circuit is now 2V+4V=6v

in series with 2Ω+14Ω=16Ω

I=6/16= 3/8= 375mA.
