Hi,
I have been given an assignment question detailing a circuit with a few resistors in as well as a capacitator.
Further more the information given was the resitance of the resitors and that the battery had had a potential difference of 9 volts.
The question's part a was workign out the current in the circuit - no problem
The problem however comes in at part b with a question on what the capacitance of the capacitator is.
Now from my understanding of capacitance you need to know the charge and use the forumal C=Q/V but I'm missing Q.
I know V = joules per coulomb but I'm not seeing the relationship to find out what Q is.
Any pointers would be greatly appreciated.
Thanks
Jacques
