Question

PHYC 240-EXAM 3-Practice Problems 3) A 2.00 nF capacitor is charged with a 60.0 V battery. The battery is then removed The charged capacitor is then attached to a 2000.0 ohm resistor at t -o. a) What is the time constant? b) How long until the the charge drops to 20% of its original value? You have an extra 2000.0 ohm resistor. How would you add it to the circuit to reduce the time constant by one half? Draw the circuit below c) Look at all those bulbs! a) 4) Rank the brightness of these bulbs from brightest to dimmest If Bulb S were replaced with a wire, what would happen to the brightness of bulb P? Explain. b) Draw an X on the diagram to indicate where you could cut the wire to increase the brightness of Q. NO NEED TO EXPLAIN c) 2 of 4
