A capacitor, in a series with a 720 ohm resistor, is being charged. At the end of 10 ms its charge is half the final value. The capacitance is about:(adsbygoogle = window.adsbygoogle || []).push({});

a)9.6 uF

b)14 uF

c)20 uF

d)7.2 uF

e)10F

Now how in the heck and I suppose to know this one. I know ohms law and I know how to find capacitance. But what does either of these has to do with time?
