Amplifier Voltage Calculator
Enter the values of input voltage, Vi(V) and gain of the amplifier, G to determine the value of Amplifier voltage, Va(V).
Amplifier Voltage Formula:
Amplifier voltage is a critical concept in electrical engineering and audio electronics, referring to the output voltage produced by an amplifier.
Gain is a measure of how much an amplifier increases the strength of the input signal.
Understanding amplifier voltage is essential for designing audio systems, signal processing, and various electronic circuits.
Amplifier voltage, Va(V) in volts is calculated by the product of input voltage, Vi(V) in volts and gain of the amplifier, G.
Amplifier voltage, Va(V) = Vi(V) * G
Va(V) = amplifier voltage in volts, V.
Vi(V) = input voltage in volts, V.
G = gain of the amplifier.
Amplifier Voltage Calculation:
- Calculate the output voltage of an amplifier with an input voltage of 2 volts and a gain of 5:
Given: Vi(V) = 2V, G = 5.
Amplifier voltage, Va(V) = Vi(V) * G
Va(V) = 2 * 5
Va(V) = 10V.
- Calculate the input voltage of an amplifier with an output voltage of 12 volts and a gain of 8:
Given: Va(V) = 12V, G = 8.
Amplifier voltage, Va(V) = Vi(V) * G
Vi(V) = Va(V) / G
Vi(V) = 12 / 8
Vi(V) = 1.5V.
Applications and Considerations:
