What happens when two or more capacitors are connected in parallel across a potential difference?
When two or more capacitors are connected in parallel across a potential difference, the total capacitance increases. This is because the equivalent capacitance of capacitors in parallel is the sum of their individual capacitances.
How does charge sharing occur between two capacitors connected in a circuit?
Charge sharing between two capacitors connected in a circuit happens when one capacitor releases some of its stored charge to the other capacitor, equalizing their voltages. This occurs until both capacitors have the same voltage across them.
What happens to capacitors that are connected in series?
When capacitors are connected in series, their total capacitance decreases. This is because the total capacitance is inversely proportional to the sum of the reciprocals of the individual capacitances. The voltage across each capacitor remains the same.
What happens in a battery's negative terminal when it is not part of a circuit?
When a battery's negative terminal is not connected to a circuit, it accumulates excess electrons, creating a negative charge. This creates a potential difference between the positive and negative terminals, which is the driving force for the flow of electric current when the battery is connected to a circuit.
What causes potential difference?
A potential difference causes an electric current. Think of it like a river : the source of water is the most elevated point of the river, so the water has a lot of gravitational potential energy. The end of the river is the lowest point of it, so the water has very low gravitational potential energy. What happens between these two points? Water flows! This analogy can be applied to electricity; the potential difference is caused, for example, by a battery in an electric circuit.

What happens to charge and potential difference and capacitance in the presence of dielectric when the battery is disconnected from the capacitors?
The capacitor will hold the charge, until it leaks off due to resistances in the dielectric or external.

If as more resistors are connected in series with the first what happens to the potential difference across each resistor?
adding resistors to a string will have the effect of decreasing each resistor voltage drop.
What happens to the current when a switch is on?
It moves to equalise a potential difference

This creates a potential difference between the positive and negative terminals, which is the driving force for the flow of electric current when the battery is connected to a circuit.
What happens when an alternating potential difference is applied across a primary coil of a transformer?
burn or burst

This analogy can be applied to electricity; the potential difference is caused, for example, by a battery in an electric circuit.
What happens when two capacitors have the same plate separation?
When two capacitors have the same plate separation, the capacitance of the capacitors will be directly proportional to the area of the plates and the permittivity of the material between the plates. This means that the capacitance of the capacitors will be the same if the area of the plates and the permittivity of the material are the same.
What happens to current in a simple circuit as potential difference is increased?
depends on the simple circuit. please describe it.
What is the flow of an electrical current in a circuit outside the power source?
Usually a circuit is connected to a power source, which could be a battery or an outlet. When this happens current flows through the circuit. The power supply raises electrical charges through the required potential difference, and then in the circuit the charges flow down the potential gradient giving up their energy.
