Problem 10: While preparing a laboratory experiment on capacitors, you connect an E-4.5 V DC power supply to fully charge an old capacitor that is marked C- 330 HF Your lab assistant hooks up the circuit as shown below. When the switch S is at point a, the capacitor is connected to the power supply. When the switch S is at point b, the capacitor is disconnected from the power supply and connected to a voltmeter, V. The voltmeter has an internal resistance R-10.0 MS2 al Otheexpertta.com Part (a) The capacitor is initially uncharged, when the switch is moved to position a, hooking the capacitor C to the power supply. What will happen to the charge on the capacitor? It will quickly (but not instantaneously) increase to a maximum value Correct! Part (b) Calculate the charge on the capacitor (in Coulombs) when it is fully charged by the power supply Part (c) After the capacitor is fully charged, you switch the switch to position b at time t-0 seconds. The voltmeter initially reads 4.5 V. After how much elapsed time (in seconds) would you expect the voltmeter to read 1/2 its initial value? Part (d) When you actually move the switch to point b, the voltmeter shows it only takes 1000.0 s for the voltage to drop to half its initial value. Which of the following are possible explanations of the observed behavior of this circuit? Select all that apply. OThe dielectric in the capacitor has degraded over time, decreasing the effective capacitance of the capacitor. OThe capacitor has been physically damaged, effectively bringing the plates closer together. OThe internal resistance of the volt-meter is significantly lower than 10 ΜΩ OThe internal resistance of the power supply is acting in series with the capacitor, decreasing the overall resistance of the circuit OThe internal resistance of the power supply is acting in parallel with the capacitor, decreasing the overall resistance of the circuit Submit Hint Feedback I give up!
