Unformatted text preview: All resistors hace the same value R. (10 pts) a) Find the current through R 2 just after the switch is closed. b) Find the current through R 2 a long time after the switch has been closed. c) DESCRIBE QUALITATIVELY how you expect the current in R 3 to behave after the switch is closed. d) Draw a sketch of the graph of I 3 vs. t for the current through R 3 after the switch has been closed until a long time after it has been closed. _ + V S R 1 R 2 R 3 C 1 C 2 4 4. Consider the circuit below. (10 pts) a) What is the total number of currents in the circuit? b) Write down the required equations to solve for all the current in the cirucit. c) Assuming the current from a to b is + 0.385mA, find the currents in the rest of the circuit. d) Find the potential of point c relative to point e. Which point is at a higher potential?...
