Consider the circuit below. Take the current I to leave the positive terminal of the 15-V battery, the current I, to leave the positive terminal of the 10-V battery, and the current l, in the tight branch of the circult to enter the top junction. (a) (1 pt) Apply the junction rule and give its resulting equation. (b) (2 pts) Apply the loop rule on the left loop and on the right loop of the circuit and glve their equations (c) (1 pt) Solve for the currents i, and la (d) (1 pt) Determine the potential difference V- V as shown on the circuit. 10 2 100 10 V 10 2 15 V a 10 2
