- When is the potential difference across a capacitor an emf?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.…An ideal parallel-plate capacitor is connected across a DC power supply, The voltage of the power supply is now increased by a factor of 5.
