Problem 2 [15 points] Consider the circuit shown below. 10 Q 9V 12 20 Q 10 Q 22V 13 (a) [6 points ] Write down Kirchoff's loop law for the top and the bottom circuits. In each case, traverse the loop clockwise, and write down the law in a form where there is a zero to the right of the "=" sign. Do not treat the loop going around the whole circuit.\f(c) [6 points ] Solve your system of equations to obtain /2. (Hint: you may find it useful to add or subtract the loop law equations.)
