For the last question I posted, the Key says the answer is 0.50 nF.
How do they get that answer?
P.S. I have Teflon being 2.1 and paper being 3.5
Since the potential between point a and b is the potential between the plates, when a capacitor is half filled with a different dielectric, then we can describe the system as t
You have two capacitors, one is 4.0 micro F the other is 2.0 micro F. You also have some wires and a 10.0 V battery.
1. Using the schematic symbols (see attachment), draw a diagram of a circuit with the two capacitors connected in series with the battery. Draw a diagram of a circuit using the same battery and capacitors with
2) The Positively Charged company uses capacitors from two different manufacturers. Historically, 60% of the capacitors come from manufacturer 1. While 90% of capacitors from manufacturer one pass quality-control checks, only 75% of the capacitors from manufacturer two pass the checks. A capacitor selected at random is found
Two capacitors, with capacitance 4.20*10^-6 F and 5.90*10^-6 F, are connected in parallel across a 660-V supply line.
The charged capacitors are disconnected from the line and from each other, and then reconnected to each other with terminals of unlike sign together.
a) find the final charge on the 4.20*10^-6 F capacit
Three capacitors each with capacitance C and a parallel combination of two resistances R each are connected in series with an ideal battery of emf V as in figure.
a) What is the time constant of the circuit?
b) If the switch is closed at time t = 0; find an expression for the current in the circuit as a function of time.
1.) You have three capacitors and a battery. How should you combine the capacitors and the battery in one circuit so that the capacitors will store the maximum possible energy?
2.) Because the charges on the plates of a parrallel-plate capacitor are of opposite sign, they attract each other. Hence, it would take positive wo
