3 Transistor and 3 LED Astable Multivibrator Circuit

This circuit is an extension of the 2 transistor astable multivibrator circuit taught in universities the world over. It can be used to produce running light effect by switching three LEDs in a sequential order. This circuit can be used to drive a triac based mains electric lights also.

Capacitor Discharge Calculator(online free)

The RC discharging circuit shows that five parameters are invloved in the discharging process; they are time t, Capacitance C, Resisitance R, the initial output voltage Vi, and the final output voltage Vf. If four of these parameters are known, then this online calculator can be used to calculate the fifth one.

Capacitor Charge and Discharge Calculator

The RC charging circuit shown on this page shows that six parameters are invloved in the charging process; they are time t, VCC supply voltage, Capacitance C, Resisitance R, the initial output voltage Vi, and the final output voltage Vf. If five of these parameters are known, then this online calculator can be used to calculate the sixth one.
