Question
In the circuit below, the currents through the four resistors are as indicated. Use the junction rule to write the equations representing the relationship between the currents at the point c. (Use the following as necessary:
I1, I6,
and
I2.)
Which currents flow into the junction and which ones flow away from the junction? Review the sign convention for currents flowing into and away from a junction. = 0
Explanation / Answer
At point C:
1. I1 left it
2. I6 left it
3. I2 enters it
Thus, the equation at junction C is
--> I2 - I1 - I6 = 0 [ANSWER]
[Leaving = negative, Entering = positive]
DONE!
