A phototransistor is similar to a regular BJT except that the base current is produced and controlled by light instead of…
The transistor in Figure is used as a switch to turn the LED on and off. For example, a square wave…
The below Figure illustrates the basic operation of a BJT as a switching device. In part (a), the transistor is in…
A transistor amplifies current because the collector current is equal to the base current multiplied by the current gain, b. The base…
Using a circuit like that shown in Figure (a), a set of collector characteristic curves can be generated that show how…
As we all know, both Silicon and Germanium are semiconductor devices. But the present trend is to use Silicon instead…
An ohmmeter can be used to check the state of a transistor i.e., whether the transistor is good or not.…
There are three leads in a transistor viz. collector, emitter and base. When a transistor is to be connected in…
The below Fig. (i) shows CE transistor circuit while Fig.(ii) shows the output characteristcs along with the d.c. load line.…
In the transistor circuit analysis, it is generally required to determine the collector current for various collector-emitter voltages. One of…
