Capacitance Meter

Capacitance Meter

Capacitors are vital components in electronics, but sometimes they are broken, or the value printed on the cap has become unreadable. Because my multi-meter does not have a capacitance measurement, I decided to make one!The principle of measuring capacitance is quite simple. The voltage of a capacitor charging through a resistor increases with time T. …
