If we connected the the positive plate of c1 to the negative plate of c2 and vice versa ?

In summary, the conversation discusses the possibility of connecting capacitors in parallel and series, and how the final charge and voltage are affected by the rearrangement of charges. The voltages across capacitors are not the same in the initial configuration, but after rearrangement, they will be equal.

Thanks.
One other question if I may ask, is those capacitors connected in parallel ?
Can we say that V1=V2 ?
 
  • #4
If capacitors are in parallel with each other, then the voltage across one capacitor is also across the other one.

so as in this picture, it's possible and it's considered parallel, right?

I'd say they were in series because a current will flow around the loop - forming a circuit.
But you wouldn't normally be trying to find equivalent capacitances in that situation.

In a steady-state those capacitors would be considered to be in parallel with each other.
But that would be after the charges have rearranged. Before that, the distinction does not mean much.

Right.
We had a homework before, we had to calculate the final charge after the rearrangement.

As I have been told, we calculate the final charge after the rearrangement then consider it to be parallel, Right ?

That's right.
In the configuration shown in the diagram, the voltages across the capacitors are not the same, because of the way the charges are arranged. After the charges have rearranged, the voltages will be the same.

Related to If we connected the the positive plate of c1 to the negative plate of c2 and vice versa ?

1. What will happen if we connect the positive plate of c1 to the negative plate of c2?

If the positive plate of c1 is connected to the negative plate of c2, this will create a closed circuit. Electrons will flow from the negative plate of c2 to the positive plate of c1, creating a current. This current can be used to power a device or perform other tasks.

2. Can we connect the positive plate of c1 to the positive plate of c2?

No, this is not possible. Connecting two positive plates together will not create a closed circuit and will not allow for the flow of electrons. This will not produce a usable current.

3. What is the purpose of connecting the positive and negative plates of two capacitors?

Connecting the positive and negative plates of two capacitors creates a circuit where current can flow. This can be used to power a device or perform other tasks that require electricity.

4. Is it safe to connect the positive and negative plates of two capacitors?

As long as the circuit is properly designed and the capacitors are of the correct voltage and capacitance, it can be safe to connect the positive and negative plates of two capacitors. However, it is always important to take proper safety precautions when working with electricity.

5. What happens if we connect the positive plate of c1 to the negative plate of c2 and vice versa multiple times?

If the connection is made multiple times, it will create a series circuit. This will increase the overall capacitance and allow for a larger flow of current. However, the voltage and capacitance of the capacitors must still be considered to ensure the circuit is safe and functioning properly.
