FREE Expert Solution

We need Kirchhoff's junction rule to solve this problem.

Kirchhoff's junction rule states that current INTO a junction is always EQUAL to current OUT of the junction.

That is,

Iin=Iout

We'll also use Kirchoff's loop rule, which is written as:

ΣV=0

We also need to know, from Ohm's law, that:

V=IR

We can get the current through the 5.00-Ω and 8.00-Ω resistors in terms of I1, I2, and I3 using the junction rule.

We then apply Kirchhoff's loop rule to the three loops visible in the circuit.
