Explanation / Answer

Question 1) From the given meaurements we observe that current is zero for both the capacitors in the DC circuit .However we see that in both the cases voltage across the capacitor is equal to the supply voltage. Hence we can conclude that capacitor acts as an open circuit in DC.

Question 2) For C1 Q1 = C1 X V1 = 5.2 uC, for C2 Q2 = C2 X V2 = 2.35 uC for C3 Q3 = 10 uC .The capacitors ability to store charge is proportional to the applied voltage with greater voltage applied capacitor will have greater charge store in it. As we see from the table that maximum charge is stored in C3 as it is parallel to the source so it will show the same value of voltage as that of the supply and hence voltage will be ideally 10 V Hence it recieves a large voltage as compared to Q1 and Q2 due to which charge stored will be large.For same voltage higher the capacitor greater is the charge stored in the capacitor

Please donot post multiple questions on the board at a time.I request you to post one by one each experiment seperately on the board
