Capacitance: (multiple choice)

In summary, when a capacitor is connected to a 6.0 V battery and then disconnected and connected to a 12.0 V battery, the charge on one of its plates stays the same (c) due to the dependence on the area of the surface of the plate. However, several assumptions would need to be made to determine the exact outcome, but it is most logical to assume that the charge would increase (A) unless more information is provided about the setup.

A capacitor is first connected to a 6.0 V battery and then disconnected and connected to a 12.0 V battery. How does the charge on one of its plates change: (a) It increases, (b) it decreases, or (c) it 1stays the same?








(c) (because the charge on the plate is
depending upon the area of the surface of the plate)


Right?? Not right?

Q=CV
but one thing is not clear, because polarity matters
 
  • #3
Now I think it's A) increases...Is this right
 
  • #4
several assumptions would have to be made, but A) seems the most logical for this question... unless it is part of a bigger problem which tells you more about the setup.
 

Related to Capacitance: (multiple choice)

1. What is capacitance?

Capacitance is the ability of a material or system to store an electric charge.

2. How is capacitance measured?

Capacitance is measured in units of Farads (F) and is typically measured using a capacitance meter or an oscilloscope.

3. What factors affect capacitance?

The capacitance of a system is affected by the distance between the two conductors, the area of the conductors, and the type of material between them (known as the dielectric).

4. How does capacitance impact electronic circuits?

Capacitance is an important factor in electronic circuits as it can affect the timing and performance of the circuit. It can also be used to filter out unwanted frequencies.

5. What are some common applications of capacitance?

Capacitors are commonly used in electronic circuits, power supplies, and in filtering and tuning circuits. They are also used in energy storage devices such as batteries and capacitors in electric vehicles.
