AC Circuits and Capacitance

It is possible to generate electricity by spinning a coil within a magnetic field.  A sinusoidal voltage is generated as a result of this spinning coil.

Read  Site Linker 31 and 40. Use Menu to find AC topics.

The animation below shows the input and output of the differentiator circuit. The signal Generator provides a 1 kHz square wave input to RC circuit. C is provided by a virtual capacitance decade box.

Vertical sensitivity = 1 volt/cm
Horizontal sensitivity  = .2 ms/cm
