Most of us needs to test electronic components while in work bench. What should you do if your multimeter s battery become weak? Here is a simple circuit to test transistors, diodes and other components. The circuit is very simple and you only need to connect the two leads of the testing components.

For example if you need to test a diode, connect the two leads to test probes in two polarities. If the LED glows while in one direction, we may conclude that the diode is good. Also we can check the transistors in a similar manner. The circuit is also useful when there is a need to check the continuity between two points.
