Question 3 (10 marks! Consider two parallel conducting wires separated by a distance d. The wires are carrying currents I1 and 12 which flow in the same direction. In order to balance the forces on the wires, a third wire is placed in the system. Where will the third wire need to be positioned, and how strong must its current be? Note: the currents 11 and 12 are not necessarily equal. Question 5 (3 marks! What is the effective capacitance of the following circuit, if C1 = 3F, C2 = 8F, and C3 = 5F? : CI?C2 l_T\""3
