IB Physics Resistors and Capacitors

/

A tutorial sheet of resistor and capacitor questions follows.

  1. An uncharged 6.0 mF capacitor is placed in series with a battery of emf 12 V. Find the charge on the capacitor after 6.0 min.
  2. A 20 pC capacitor is connected in series to a 20Ω resistor. The initial charge on the capacitor is 2.0 mC. Find the charge on the capacitor after 20.0 s.
  3. A battery of emf 12.0 V and internal resistance 2.0 Ω is used to charge a 600 pF capacitor for 5.0 min. The capacitor is initially uncharged. Find (a) the work done by the battery in the 5.0 min, (b) the energy stored in the capacitor after 5.0 min.
