Problem 3: For what emf & does the 2002 resistor in Fig.3 dis- sipate no power? Should the emf be oriented with its positive terminal at the top or at the bottom? a) If the 200 S2 resistor dissipates no power, what does this mean for the distribution of the currents in the circuit? In other words, how are the currents through the different resistors related in this case? S

In other words, how are the currents through the different resistors related in this case? SOV 10052 ww 20052 30052 £? FIG. 3: The scheme for Problem 3 b) Choose any two different closed loops in the circuit and write down the Kirchhoff's loop law for these loops. It must be possible to solve these two equations for the current and the emf E. 3
