Hi,(adsbygoogle = window.adsbygoogle || []).push({});

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
