The output voltage of an amplifier is the amplified version of the input signal, determined by the voltage gain of the amplifier. It represents the voltage level at the output terminal when an input voltage is applied.
The calculator uses the formula:
Where:
Explanation: The output voltage is simply the product of the voltage gain and the input voltage, representing the amplification factor applied to the input signal.
Details: Calculating output voltage is essential for designing and analyzing amplifier circuits, ensuring proper signal amplification, and preventing signal distortion or circuit damage.
Tips: Enter voltage gain (a dimensionless value) and input voltage in volts. Both values must be positive numbers greater than zero.
Q1: What is voltage gain in an amplifier?
A: Voltage gain is the ratio of output voltage to input voltage, indicating how much an amplifier increases the voltage level of a signal.
Q2: Can voltage gain be less than 1?
A: Yes, some amplifiers (like buffer amplifiers) have voltage gain close to 1, while attenuators have gain less than 1, reducing the signal amplitude.
Q3: What are typical voltage gain values?
A: Voltage gain values vary widely depending on amplifier type - from unity gain (1) in buffers to thousands in high-gain operational amplifiers.
Q4: Does this formula work for all amplifier types?
A: This basic formula works for linear amplifiers operating within their specified range. Non-linear amplifiers or those with frequency-dependent gain require more complex calculations.
Q5: How does output voltage relate to power output?
A: Output power depends on both output voltage and current delivered to the load (P = V×I). Higher output voltage typically means higher power output for a given load impedance.
