Demonstration

Shuttling ball experiment. With a constant p.d., move the plates to different distances apart and measure the number of shuttles per second (of the ball) and the current. Then fix the distance between the elecrode plates, vary the p.d. and measure the number of shuttles per second (of the ball) and the current.

Resources

Analysis

On the lap tops, plot graphs of current against number of suttles per second.

Equipment

1x shuttling ball apparatus.

Safety

High voltages are used.
