Question

1.) Which one of the following conditions is always correct regarding the indicated currents?

a ) I1+I2?I3=0
b ) I1?I2?I3=0
c.) I1?I2+I3=0
d.) I1+I2+I3=0
e.) None of the above.

2.) Which one of the following conditions is always correct regarding the voltage drops?

a.) I1R1?I2R2=0
b.) V?I1R1?I3R3=0
c.) I1R1?I2R2?I3R3=0
d.) None of the above.

The circuit diagram shows two identical voltage sources and three resistors in a network, as well as assumed current directions through the resistors. Which one of the following conditions is always correct regarding the indicated currents?

Explanation / Answer

1) I in - I out = 0

look at bottom junction

I1 - I2 - I3 = 0

so b)

2) consider left loop

then -I1 R1 + V - I3 R3 = 0

so b)
