Capacitor discharge

The animation shows the voltage variation with time during the discharge of a capacitor through a resistor.

Use the input field below to vary the value of the the resistor through which the capacitor discharges. You must enter a value between 0 and +1000 Ω. Try 100 Ω to start with.

Then press START to run or restart the animation.

Press RESET before entering a new vaue of R.
