Question
Please choose the right answer and simplely prove it.
[31] Putting a dielectric between the plates of a capacitorinstead of vacuum will a) Weaken the electric field for a given charge on the plates. b) Increase the potential difference between the plates for a given charge. c) Decrease the potential difference for a given electric field strength. d) Change the capacitance, not the electric field. e) Not change the electric field or the capacitance. [32] When charging or discharging, the charge on a capacitor changes a) Linearly. b) At a rate proportional to the charge. c) By decaying exponentially towards the final charge. d) At a rate proportional to the charge squared. e) Logarithmically. Mark all that apply. 133] A capacitor which has zero charge on the plates is connected to a battery. The current flows as if the capacitor were a) A wire initially. b) An open circuit initially c) A wire after a long time. d) An open circuit after a long time. e) An open circuit at all times. Mark all that apply. [34] Any two capacitors in series have a) The same potential difference across them. b) The same charge on the plates. c) Different charges and potential differences. d) The same charges and the same potential differences. e) None of the above. 135] Two capacitors have the same dielectric material between their plates and are wired in identical circuits in series with a battery and resistor. If they have the same volume between the plates, then a) They will have the same voltage when fully charged. b) They will have the same charge on the plates when fully charged. c) They have the same capacitance. d) They will have the same electric field between the plates. e) None of the above.Explanation / Answer
31) a[ dilectric will create induced electric field whic is opposite to the elctric field created by charge on capictor]
32) C [ see the euation of charging or discharging]
33) A,d
34)B
35)A
tell me in which part explanation is reqiured
