A parallel plate capacitor is connected across a variable mains supply. If the potential on theplates is increased from 20 V to 100 V, the increase in capacitance of the capacitor is

A parallel plate capacitor with a capacitance of 2 µF is connected to a 100 V battery. If the separation between the plates is doubled, the capacitance is:a) 1 µFb) 4 µFc) 0.5 µFd) 2 µF

A parallel plate air capacitor is charged to a potential difference of V volts. After disconnecting the charging battery the distance between the plates of the capacitor is increased using an insulating handle. As a result the potential difference between the plates(a) increases

A capacitor is charged to a potential difference 𝑉V. If the dielectric constant 𝐾K of the dielectric material inserted between the plates is 4, the new potential difference across the plates is:a) 𝑉44V​ b) 4𝑉4Vc) 𝑉22V​ d) 𝑉V

The capacitance between two plates increases with*1 pointShorter plate area and higher applied voltageShorter play area and shorter distance between themLarger plate area, longer distance between plates and higher applied voltageLarger plate area and shorter distance between plates

A parallel plate capacitor initially has a voltage of 400V, and stays connected to a battery. If the plate spacing is doubled, what happens? 1. the voltage decreases 2. the voltage increases 3. the charge decreases 4. the charge increases 5. both voltage and charge change
