When a condenser discharges electricity, the instantaneous rate of change of the voltage is proportional to the voltage in the condenser.

Suppose you have a discharging condenser and the instantaneous rate of change of the voltage is 1/100 of the voltage (in volts per second). How many seconds does it take for the voltage to decrease by 90%?

2. Relevant equations

e^-rt

3. The attempt at a solutionLog 90= e^-t ? = 4.49?
