PHYS 206.001: Electricity and Magnetism Assignment: Week 11 / Tuesday 1. (25 points) (Problems 13 in textbook / Chapter 28) (a) Find the equivalent resistance between points a and b in the figure below. (a) Calculate the current in each resistor if a potential difference of 34.0 V is applied between points a and b. 2. (25 points) (Problems 30 in textbook / Chapter 28) In the circuit below, determine (a) the current in each resistor and (b) the potential difference across the 200 Ω resistor. 1 3. (25 points) (Problems 43 in textbook / Chapter 28) The circuit shown below has been connected for a long time. (a) What is the potential difference across the capacitor? (b) If the battery is disconnected from the circuit, over what time interval does the capacitor discharge to one-tenth its initial voltage? 4. (25 points) (Problems 45 in textbook / Chapter 28) A charged capacitor is connected to a resistor and switch as shown below. The circuit has a time constant of 1.50 second. Soon after the switch is closed, the charge on the capacitor is 75.0 % of its initial charge. (a) Find the time interval required for the capacitor to reach this charge. (b) If R = 250 kΩ, what is the value of capacitance C? 2
