Capacitor charging graph

[Alan72]

Thanks for the assist.

I started with an exponential graph and gradually added the variables, checking each time before adding the next. It was the time t variable that caught me out until I took your suggestion and renamed it x. Makes sense really as the x value increases to give me my curve.

The rest of the formula didnt change, for instance, the size of resistor was constant so I had figures for all of these.

Thanks again. Not sure how to mark this as solved but SOLVED!!
