Please help! Capacitance question!
Does the capacitance increase, decrease, or stay the same if:
1. the charge on the plate doubles?
2. the potential difference across the plates triples?
3. the distance between the plates is halved?
4. area of the plates is doubled?
5. electric field is reduced by half.
My answers are
1. increases
2. decreases
3. increases
4. increases
5. same
Are these correct?
Also, True or false: "Charging a parallel plate capacitor requires no work provided the charges placed on the two plates are equal and opposite." Provide appropriate reasoning.
