Hello guys,

Here is a question from my Physics HW. Please answer the question fully including the sub-questions as well. Remeber, the rule on this website is 1 question and up to 4 subparts. Also please make sure the answer correct. High rating will be included to the first and correct answers also if your answer is incorrect, rest assured I will downrate and report.

*NOTE* do not write in CURSIVE because I cannot read it. Sorry for being picky.

3. A junction of circuit is shown below with five connecting wires. The figure shows the value and direction of four of the current Determine the current fiowing from the fifth wire and indicate if it is flowing into or out of the junction. o points) 4A 5 A

Explanation / Answer

3.

according to kirchoff's junction law , sum of current at a junction is 0

assuming current coming towards junction as positive and currents going away from junction as negative

I1 + I2 + I3 + I4 + I5 = 0

1 + 5 + (-4) + (-3) + I5 = 0

I5 = 1 A

since the current is positive , it is flowing into
