Three parallel plate capacitors (C1,C2 and C3 ) are in series with a battery of 100 V. C1=2500 micro Farad; C2=2C1 , C3=3C1 .
(a) What is the potential difference over each capacitor and how much charge is on each capacitor?
Across C1 :V1 (in Volts) =
incorrect
Q1 (in C) =
incorrect
Across C2 :V2 (in Volts) =
incorrect
Q2 (in C) =
incorrect
Across C3 : V3 (in Volts) =
incorrect
Q3 (in C) =
incorrect
(b) We now connect a 4th parallel plate capacitor ( C4=4C1 ) to the battery. One side of the capacitor is connected to the negative side of the battery, the other side is connected to the positive side of the battery.
What is the potential difference over each of the 4 capacitors and what is the charge on each?
Across C1 : V1 (in Volts) =
incorrect
Q1 (in C) =
incorrect
Across C2 : V2 (in Volts) =
incorrect
Q2 (in C) =
incorrect
Across C3 : V3 (in Volts) =
incorrect
Q3 (in C) =
incorrect
Across C4 : V4 (in Volts) =
incorrect
Q4 (in C) =
incorrect
(c) We make one more change: We still have our 4 capacitors as above, but we now place a dielectric (K = 3) between the plates of the 4th capacitor.
What is the potential difference across C4 and what is the charge on it?
Across C4 : V4 (in Volts) =
incorrect
Q4 (in C) =
