In this we are going to make and study about simple continuity circuit. In electronic field multimeter is the very usefull instrument. Continuity testing is used in electronic circuits for the continuity check. It is the part of multimeter function. Here we sepperating the continuity function of multimeter. It consist of a simple LED , resistor and 9V power supply. The two legs are place where the continuity to be measured. If the circuit is closed the LED will glow. Otherwise it continue without glow. It is very simple to use .

 Components for wiring this circuit

 R - 350K
 9V battery
