What is the primary function of an operational amplifier (op-amp)?
To amplify voltage signals
To convert AC to DC
To store electrical energy
To measure resistance
Answer explanation
The primary function of an operational amplifier (op-amp) is to amplify voltage signals. It is designed to increase the amplitude of input signals, making it essential in various electronic applications.

In an inverting amplifier configuration, what is the phase difference between the input and output signals?
0 degrees
90 degrees
180 degrees
270 degrees
Answer explanation
In an inverting amplifier, the output signal is inverted relative to the input. This means there is a phase difference of 180 degrees between the input and output signals, making 180 degrees the correct choice.

Which of the following is the formula for the voltage gain of an inverting amplifier?
Answer explanation
The voltage gain of an inverting amplifier is given by the formula -Rf/Rin. This indicates that the output voltage is inverted and scaled by the ratio of the feedback resistor (Rf) to the input resistor (Rin).

In a non-inverting amplifier, if the input voltage is 2V and the gain is 5, what is the output voltage?
2V
5V
10V
15V
Answer explanation
In a non-inverting amplifier, the output voltage (Vout) is calculated using the formula Vout = Vin * Gain. Here, Vin = 2V and Gain = 5, so Vout = 2V * 5 = 10V. Therefore, the correct answer is 10V.

What is the gain-bandwidth product of an op-amp?
The product of the gain and the bandwidth
The sum of the gain and the bandwidth
The difference between the gain and the bandwidth
The ratio of the gain to the bandwidth
Answer explanation
The gain-bandwidth product of an op-amp is defined as the product of the gain and the bandwidth. This means that as the gain increases, the bandwidth decreases, keeping the product constant.

Which component is primarily responsible for providing feedback in an op-amp circuit?
Capacitor
Resistor
Inductor
Diode
Answer explanation
In an op-amp circuit, the resistor is primarily responsible for providing feedback. It sets the gain and stabilizes the output by controlling the amount of output voltage fed back to the inverting input.

What is the typical unit of measurement for the gain-bandwidth product?
Hertz (Hz)
Decibels (dB)
Volts (V)
Amperes (A)
Answer explanation
The gain-bandwidth product is typically measured in Hertz (Hz), as it represents the frequency range over which an amplifier can operate effectively. Other units like dB, V, and A are not suitable for this measurement.
