Abstract

* In this research we have formed a circuit to exam the transistors of the types npn and pnp and detect the transistors that work from the damage .

* We used the formation of this circuit on the basic component is the 555 timer , and we used several other pieces of electronic will come to mention later.

* We tested many transistors by the previous circuit.
