Variable Plate Capacitor

Investigate the Q = CV relationship with our simple device, so named because the two plates can be moved closer or further away from each other. The farther the plates are from each other, the less electricity can be stored, as the capacitance increases when the distance between the plates decreases. Consists of two smooth plates mounted on insulated supports that slide along an extrusion. The distance between the plates can be controlled with an adjusting knob. We include leads for attaching to a multimeter. Instructions include experiments. Needs multimeter, banana plug cables, power supply, calipers.
