thread moved into homework forum, so comes without template
Please help how Ve is calculated what i think is that it should be:
-Ve=-Vee+IeRe;
How Ve is taken positive please someone draw equivalent circuit for same
There is no open loop.karandeepdps said:Last line,how they have applied kvl to an open loop.
KVL loop in BJT biasing refers to the application of Kirchhoff's Voltage Law in the analysis of a bipolar junction transistor (BJT) circuit. It involves tracing the path of voltage drops in a closed loop within the circuit to determine the voltage across each component.
KVL loop is important in BJT biasing because it allows us to accurately calculate the voltages at various points in the circuit. By following the voltage drops in a closed loop, we can determine the proper biasing conditions for the transistor and ensure it operates within its desired range.
To apply KVL loop in BJT biasing, you first need to identify the closed loop in the circuit. Then, starting from any point in the loop, assign a direction of current flow and label the voltage drops across each component according to this direction. Finally, use Kirchhoff's Voltage Law to set up and solve the equations for the loop.
Yes, KVL loop can be used for both NPN and PNP transistors. However, the direction of current flow and the polarity of the voltage drops will be opposite for these two types of transistors. It is important to keep this in mind when applying KVL loop in BJT biasing for different transistors.
KVL loop is based on the assumption that the voltage drops across each component in the loop are known. However, in real-world circuits, these voltage drops may vary due to factors such as temperature and manufacturing tolerances. Therefore, KVL loop may not always provide completely accurate results and should be used in conjunction with other analysis methods to ensure accurate biasing of the BJT.
