Why does the voltage reading drop in measuring the potential difference across the capacitors?
Because the capacitor discharges. so voltage across the capacitor decreases.
Is it true that a capacitor is initially uncharged the potential difference across it is zero?
yes
How is the change of potential difference across the capacitor determined?

Use second order differential equation to solve RCL series circuit?
we use charge stored in the capacitor as our variable (remember it one of the three variable). so the potential difference across the capacitor is --charge stored in the capacitor at that instance/capacitance of the capacitor. potential difference across resistor is --resistance* differential of charge with respect to time. potential difference across inductor is -- inductance*double difference of charge with respect to the time. If there is no voltage source attached with the network then sum of the total potential difference is equal to zero hence your solution.........L*d^2(q)/dt^2 + R*d(q)/dt + q/c =0
How can works capacitors?
When connected to a d.c. supply, electrons are transferred from one plate and deposited on the opposite plate. This creates a potential difference across the two plates. This action continues until the capacitor's potential difference is equal (but opposite) to the potential difference of the d.c. source. If the source is then removed, the electrons cannot return to the original plate, other than through the dielectric, so the capacitor will hold that potential difference. By definition, the charge 'stored' on the capacitor is the amount of negative charge on the negative plate (not the sum of the charges on the two plates). Leakage current through the dielectric gradually reduces the potential difference across the plates.
A step-down transformer has 525 turns in its secondary and 12500 turns in its primary If the potential difference across the primary is 3510 V what is the potential difference across the secondary?
The potential difference across the secondary coil will be 147.42 Volts
Name a device that helps to maintain a potential difference across a conductor?
volt meter is the device that helps to maintain a potential difference across a conductor
What is the potential difference across a single 4 Ohm resistor if the source voltage is 230v?
the potential difference across the single 4ohm resistor is 230volts.

What is the potential difference across a 1500 ohm resistor carrying a current of 0.075 A?
Potential Difference across a resistor is given by, Potential Difference = Resistance * Current = 1500 * 0.075 = 112.5 Volts
Why potential difference is same for each capacitive connected in parallel combination?
Because it is simple phenomenon of electricity everything(resistance,capacitor,inductor) connected in parallel holds the same voltage across the each parallel element.
What is the difference between diffusion potential and nernst potential?
The Diffusion Potential is the potential difference across the boundary b/w two electrolytic solutions of different compositions The Nernst Potential is the diffusion potential across a membrane that exactly opposes the net diffusion of a particular ion through the membrane
