Capacitors in Combination Problems:
1. A 20- and a 25-pF capacitors are connected in parallel, and a potential difference of 100V is applied to the combination. Find the charge on each capacitor and the potential difference across it.
Answer:
q1 = 2x10^-9C; q2 = 2.5x10^-9C; V1 = V2 = 100V
2. A 50- and a 75-pF are connected in series, and a potential difference of 250V is applied to the combination. Find the charge on each capacitor and the potential difference across it.
Answer:
q1 = q2 = 7.5x10^-9C; V1 = 150V; V2 = 100V
3. Two capacitors of capacitance 2.0 and 4.0uF are connected in parallel. This group is connected in series with a 3.0 uF capacitor across an 800-V line. Find the potential difference across each capacitor.
