Enter the attenuator input voltage (volts), the attenuator resistance 1 (ohms), and the attenuator resistance 2 (ohms) into the Attenuator Output Voltage Calculator. The calculator will evaluate the Attenuator Output Voltage.

## Attenuator Output Voltage Formula

The following formula is used to calculate the Attenuator Output Voltage.

AOV = Vin * R1 / (R1+R2)

Variables:

• AOV is the Attenuator Output Voltage (volts)
• Vin is the attenuator input voltage (volts)
• R1 is the attenuator resistance 1 (ohms)
• R2 is the attenuator resistance 2 (ohms)

## How to Calculate Attenuator Output Voltage?

The following steps outline how to calculate the Attenuator Output Voltage.

1. First, determine the attenuator input voltage (volts).
2. Next, determine the attenuator resistance 1 (ohms).
3. Next, determine the attenuator resistance 2 (ohms).
4. Next, gather the formula from above = AOV = Vin * R1 / (R1+R2).
5. Finally, calculate the Attenuator Output Voltage.
6. 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.

attenuator input voltage (volts) = 30

attenuator resistance 1 (ohms) = 5

attenuator resistance 2 (ohms) = 6

AOV = Vin * R1 / (R1+R2) =  ?
