A conductor is charged by a battery and then disconnected.How are the capacitance, potential difference and stored energy related to the capacitor affected if The distance between the plates is decreased. |
|
Answer» Solution :Capacitance of a PARALLEL plate capacitor, `C= (k in_0alpha)/(d)` If the distance between the plates is decreased, capacitance C of the capacitor will increase.Since the charge remains constant, due to increase of capacitance, the POTENTIAL difference between the plates `(V=(Q)/(C ))` and the ENERGY STORED in the capacitor `(U= (1)/(2) (Q^2)/(C ))` will decrease. |
