Question

Which is the best technique to use when testing a transistor?

Answer 1

احد Let us consider a Diode Anode cathode (it shows s.tv reading it The best way / technique to testing a transistor. > with the help of multimeater we can read the voltage values between Base (8] and Emmitterelor) Base [B] and collector (c] if the voltage value shows 0.7V the transistor works in good condition - For a bipolar junction transistor VBE is approximately 0.7v for a Silicon transistor. > For a germanium transistor ve is approximately 0.01 transistor VBE

we can notice these two trans- PnP Transistor Je & Eeln/p/c+ - Firstly we have to place a transistor on bread board - in multimeter we have to switch I the Diode mode. I by connecting a positive terminal to Emmitter and negative terminal ! to Base we observe the voltage values. > next by connecting positive terminal to collector and negative terminal to base we can observe the voltage value. They show the value 0.7 volts » I nearly. > from these we can conclude that it is a Php transistor.

2 npn Transistor I - by connecting a positive terminal to Base (B] and negative terminal to collector (c] we can observe the voltage value. next by connecting a positive terminal to Base (0] and negative terminal to Emitter (E] we can observe the voltage value. They shows the voltage o.zv. - nearly. I I from these we can conclude that it is a non transistor.
