SAWTOOTH GENERATOR (OP-AMP BASED)
Objectives of this experiment:
To demonstrate the operation of circuit, which can produce linear ramps. Linear ramp is produced by charging a capacitor from a constant voltage source. The linearity is limited to a small charge curve portion which is produced by charging a capacitor from a constant current source. The Ramp has better linearity. This experiment demonstrates both methods of forming a ramp.

Van de Graaf Generator, Large
| Create your own lightning with these time-tested devices that have delighted students for decades! Named after the inventer Van de Graaf, an American physicist, this machine produces low-amperage static electricity that can be “shocking” but perfectly safe. Two different pulleys inside a plastic column create and carry static charge up to the polished alumimun collector globe. You can draw out this static charge in a burst of lightning - or you can set each hair on your head on end! Our instruction booklet tells you how to raise hair; produce lightning and electric wind; experiment with St. Elmo’s fire or electrostatic attraction and repulsion. |
