What happens to capacitance and potential difference of a parallel plate capacitor The distance between the two plates is decreased?
Because the capacitor is still connected to the power supply the potential difference can’t change. Moving the plates further apart decreases the capacitance, also reducing the charge stored by the capacitor.
What will be the change in capacitance of a capacitor if the distance between the plates of the capacitor is decreased?
when distance is decreased between plates the capacitance value would increase.
When the plates of a charged parallel plate capacitor are brought closer the potential difference between the plates A decreases B increases C remain same D becomes zero?
A parallel plate capacitor is first charged and then distance between the plates is increased. In this process electric field between the plates remains the same, while potential difference gets decreased.
What do you think will happen to the capacitance if the space between the plates decrease?
Capacitance is directly proportional to the electrostatic force field between the plates. This field is stronger when the plates are closer together. Therefore, as the distance between the plates decreases, capacitance increases.
What is the effect of capacitance of a capacitor if the area of the plate increased by 2 times and the distance between the plates increased by 2 times?
k=dielectric constant of the medium between the two parallel plate and d=distance between the two parallel plate. if the area between two plate is increasing that means d is increasing and hence the overall capacitance will be decreased.
What will be the change in energy stored in the capacitor if separation between the plates is doubled after disconnecting it from the battery?
As seen in the equation, the energy of the capacitor is directly proportional to the separation between the plates. Hence doubling the plate separation after disconnecting the battery, the energy will be doubled.
