## Homework Statement

My (practise) coursework is to test the equation 'V = Vo e

^{-t/RC}' and choose values of R and C so that the voltage across the capacitor falls to half in 15 seconds. I decided it would be too difficult and inaccurate to record the voltage across the capacitor every 5 seconds, so I chose 10. However, I'm not sure if this will get me enough readings.

## Homework Equations

V = Vo e

^{-t/RC}

## The Attempt at a Solution

I decided it would be too difficult and inaccurate to record the voltage across the capacitor every 5 seconds, plus having a small time interval would give a larger percentage error, so I chose 10. However, I'm not sure if this will get me enough readings if the voltage is going to halve in 15 seconds. However, I know the rate of discharge will decrease, so it may be suitable anyway. Does anyone have any suggestions?
