B 2007 b 3 . In the circuit above, a 12.0 V battery is connected to two resistors, one of resistance 1000Ω and the other of resistance 500Ω. A capacitor with a capacitance of 30×10−6F is connected in parallel with the 500Ω resistor. The circuit has been connected for a long time, and all currents have reached their steady states.
a. Calculate the current in the 500Ω resistor.
b. i. Draw an ammeter in the circuit above in a location such that it could measure the current in the 500Ω resistor. Use the symbol (A) to indicate the ammeter.
ii. Draw a voltmeter in the circuit above in a location such that it could measure the voltage across the 1000Ω, resistor. Use the symbol (V) to indicate the voltmeter.
c. Calculate the charge stored on the capacitor.
d. Calculate the power dissipated in the 1000Ω resistor.
e. The capacitor is now discharged, and the 500Ω resistor is removed and replaced by a resistor of greater resistance. The circuit is reconnected, and currents are again allowed to come to their steadystate values. Is the charge now stored on the capacitor larger, smaller, or the same as it was in part c.?
