The following equations describe an electric circuit.

−I1(236 Ω) + 5.80 V − I2(400 Ω) = 0
I2(400 Ω) + I3(150 Ω) − 3.10 V = 0
I1 + I3 − I2 = 0

(a) Draw diagram of the circuit. Identify the physical meaning of each unknown on your drawing.

(b) Calculate the unknowns (in mA). With respect to the 5.8 V battery, consider current moving toward the positive pole as positive and current moving toward the negative pole as negative.

I1= _____mA

I2=_____ mA

I3= _____mA
