Q2. What is op amp follower
Ans. 
Op amp follower is a circuit configuration where the output voltage follows the input voltage.
• Op amp follower has unity gain, meaning the output voltage is the same as the input voltage.

• It is also known as voltage follower.

• Op amp follower is commonly used as a buffer to isolate two circuits with different impedance.

• It has high input impedance and low output impedance.

• Op amp follower is used in audio amplifiers, voltage

Q1. Draw Voltage divider circuit, circuit of inverting op amp,rectifier circuit
Ans. 
Voltage divider circuit is used to divide a voltage into smaller parts, inverting op amp circuit amplifies and inverts the input signal, rectifier circuit converts AC to DC.
• Voltage divider circuit consists of two resistors connected in series, with the output taken from the connection point.

• Inverting op amp circuit has the input signal connected to the inverting input terminal and feedback resistor connected between ou...read more
