Product Summary

The Charge/Discharge Circuit offers a unique way to observe and measure the behavior of DC circuits including batteries, capacitors, light bulbs, and resistors. It also includes an open slot that allows a component to be inserted for further experimentation.

Works Like a Variable DC Power Supply

Charge the capacitor using batteries and then the capacitor will act as a variable DC power source as you discharge it through a resistor or light bulb. Students measure the voltage

and current as the capacitor discharges, and they can graph the relationship between voltage and current for various components.
