In two ofee wines currents 1.65 A and b-2.85 A enter the junction. In one wires oument b 695 A leaves the juncton Find the aument in the fourth and indicate its direction, O Undetermined out ol the unction O into the Runcton

Explanation / Answer

Use Kirchoff's current law.

Total Current entering a junction = Total Current leaving it

so, I1 + I2 = I3 + I4

=> 1.65 + 2.85 = 6.95 + I4

=> I4 = - 2.45 A

so, the current in the fourth wire is 2.45 A and it is entering the junction.
