Enter the input and output voltages into the calculator to determine the gain of a resistor. The gain is a unitless value that represents the ratio of output voltage to input voltage in a resistor circuit.
Resistor Gain Formula
The following formula is used to calculate the gain of a resistor.
G = Vout / Vin
Variables:
- G is the gain (unitless)
- Vout is the output voltage (V)
- Vin is the input voltage (V)
To calculate the gain of a resistor, divide the output voltage by the input voltage.
What is Resistor Gain?
Resistor gain is a measure of how much a resistor circuit amplifies the input voltage to produce the output voltage. It is a crucial parameter in electronic circuits, especially in amplifiers, where precise control of voltage gain is necessary for the circuit’s performance. The gain is typically a unitless value, as it is the ratio of two voltages.
How to Calculate Resistor Gain?
The following steps outline how to calculate the Resistor Gain.
- First, measure or determine the input voltage (Vin) to the resistor circuit.
- Next, measure or determine the output voltage (Vout) from the resistor circuit.
- Use the formula G = Vout / Vin to calculate the gain.
- Finally, compare the calculated gain with the desired gain for your application to ensure the resistor circuit is operating correctly.
- After inserting the variables and calculating the result, check your answer with the calculator above.
Example Problem :
Use the following variables as an example problem to test your knowledge.
Input voltage (Vin) = 2 V
Output voltage (Vout) = 10 V
