Download Solution PDFIn an Op-Amp inverting amplifier, the pin 2 of 741 IC is at virtual ground. This statement is based on which law?
Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFOp-amp:
This IC is Dual Inline Package and it is represented as 741 IC.
The pin diagram is shown below:
Pin 2 and 3 are input terminals.
Inverting terminal:
If we apply the input at this terminal the output will have a 180° phase shift.
Non-inverting terminal:
If we apply the input at this terminal the output will not have any phase shift at the output.
Kirchhoff’s Voltage law:
This law states that the algebraic sum of all voltages in a closed loop will be zero.
\(\sum {V_{loop}} = 0\)
Virtual ground:
Both the terminal voltages will be equal for an op-amp.
Here we are discussing the voltage and in a loop, it will be zero.
V1 = V2
V1 – V2 = 0
