Which statement is correct?a)BJT and MOSFET are current controlled dev...
Answer:
BJT and MOSFET are two types of transistors used in electronic circuits. Both these transistors are used for amplifying or switching signals. However, they differ in their mode of operation and the way they are controlled.
D. BJT is current controlled and MOSFET is voltage controlled device
BJT stands for Bipolar Junction Transistor. It is a current-controlled device, which means the input current controls the output current. BJT has three regions - emitter, base, and collector. When a small current flows through the base terminal, it controls the larger current flowing through the collector and emitter terminals. The output current of the BJT is proportional to the input current.
MOSFET stands for Metal-Oxide-Semiconductor Field-Effect Transistor. It is a voltage-controlled device, which means the input voltage controls the output current. MOSFET has three terminals - gate, source, and drain. When a voltage is applied to the gate terminal, it creates an electric field that controls the flow of current between the source and drain terminals. The output current of the MOSFET is proportional to the input voltage.
In conclusion, BJT is a current-controlled device, and MOSFET is a voltage-controlled device. It is important to understand the difference between these two types of transistors to choose the right one for a specific application.
