How to Use This Calculator
- Enter the input voltage (Vin) in volts. This is the voltage applied to the amplifier's input.
- Enter the amplifier gain (A). This is a dimensionless value representing how much the amplifier boosts the input signal (e.g., gain of 10 means the output is 10 times the input).
- Enter the load resistance (Rl) in ohms. This is the resistance connected to the amplifier's output.
- Click the "Calculate" button to compute the output voltage and efficiency.
- The calculator will display the output voltage and the voltage gain efficiency.
Understanding Amplifier Voltage Concepts
The output voltage of an amplifier is calculated as:
Vout = Vin × A × (Rl / (Rl + RL))
Where:
- Vout = Output Voltage
- Vin = Input Voltage
- A = Amplifier Gain
- Rl = Load Resistance
- RL = Internal Resistance of Amplifier
In this calculator, we're assuming an ideal amplifier with zero internal resistance (RL=0), which simplifies the formula to Vout = Vin × A.
