1. What is the Amplifier Output Equation?

The amplifier output equation calculates the output voltage of an amplifier by multiplying the input voltage by the voltage gain. This fundamental relationship is key to understanding amplifier behavior in electronic circuits.

2. How Does the Calculator Work?

The calculator uses the amplifier output equation:

Where:

• \( V_{out} \) — Output voltage (V)
• \( V_{in} \) — Input voltage (V)
• \( A_v \) — Voltage gain (dimensionless)

Explanation: The equation shows the direct proportional relationship between input voltage and output voltage, scaled by the amplifier's gain.

3. Importance of Output Voltage Calculation

Details: Calculating output voltage is essential for designing amplifier circuits, ensuring proper signal levels, and preventing distortion or damage to downstream components.

4. Using the Calculator

Tips: Enter input voltage in volts and voltage gain (a positive number). Both values must be valid (greater than 0).

5. Frequently Asked Questions (FAQ)

Q1: What is typical voltage gain range?
A: Gain can range from less than 1 (attenuation) to thousands, depending on amplifier type and configuration.

Q2: Does this work for AC signals?
A: Yes, for instantaneous values. For RMS calculations, use RMS input voltage.

Q3: What affects real-world amplifier output?
A: Power supply limits, bandwidth, input impedance, and nonlinearities can affect actual output.

Q4: How does this relate to dB gain?
A: Voltage gain in dB is 20×log₁₀(A_v). This calculator uses linear gain.

Q5: Can this calculate current gain?
A: No, this calculates only voltage gain. Current gain depends on input/output impedances.
