# Strange Graph Question Watch

1. Hey Guys,

Any useful hints/guidance would be great because I'm having real trouble with it.

So...

A resistor of 1000 ohms is connected in series with a 200 microfarad capacitor and supplied with direct voltage of 10V from a battery. Draw a graph of time in seconds against the potential difference across the capacitor after 0.4s.

Cheers

OP: This is not a criticism at all since you are new to the boards: it would help greatly when posting in future, for you to also post your workings on the problem and a brief explanation as to why you are having difficulty in answering / understanding the problem and/or concepts.

That way, people will have a good idea on how best to guide you without either patronising you or jumping in way over your head!

To get you started, do you understand/have you covered the equations for charge/discharge cycles for voltage/current/charge accumulated on the capacitor?

Hint: They involve exponential laws for charging and discharging.
