- Homework Statement
- Need to calculate the voltage and current for a circuit

- Relevant Equations
- KCL and KVL equations , V=IR

I am trying to find voltages and currents of the below circuit,

3.3 -22000*I2 - 2200(I2-I3) = 0

3.3 -24200*I2 + 2200*I3 = 0 -> eq1

-(10 - I3)*1500 - (I2 - I3)*2200 = 0

-15000 + 1500*I3 - 2200*I2 + 2200*I3=0

-15000 - 2200*I2 + 3700*I3=0 -> eq2

Solving equations 1 and 2 i get I2=0.38 Amps and I3 = 4.28 Amps

I assume i have completely gone wrong in calculations, can current I3 flow into the source. Please help.
