QUESTION
When a condenser discharges electricity, the instantaneous rate of change of the voltage is proportional to the voltage in the condenser.
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 -0.01 of the voltage (in volts per second). How many seconds does it take for the voltage to decrease by 90 %?
