Question
6. Two capacitors in parallel Before connecting two fully discharged capacitors in parallel and charging th gh a round em up throu bulb, as shown, discuss with your partner how you think the charging time wil with one capacitor. (a) Set up the circuit. How does the time to charge two capacitors in parallel compare to the time to charge one capacitor? longer shorter same time (b) Explain your result. (c) How does the charge stored on each capacitor compare to the charge stored on a single capacitor that it is charged up by itself with one round bulb and two batteries (as in 1 in Part 1)? same more less (d) How would you check? (Do not use the ammeter.)Explanation / Answer
a) The time taken to charge two capacitors will be longer because we need to draw current for more time to accumulate more charge.
b) Current is rate of charge, so charge equals the product of current and time. So more charge requires more time.
c) The charge stored on the capacitors will be same as the case when 1 capacitor is connected.
d) We see that capacitors ends are connected to battery and resistance , so finally when current stops flowing the voltage in the capacitoe equals the battery voltage in both cases.
