Enter the input voltage, resistance, and total resistance into the calculator to determine the output voltage. This calculator helps in understanding how voltage is attenuated in a resistive circuit.
Voltage Attenuation Formula
The following formula is used to calculate the output voltage after attenuation.
V_out = (R / R_total) * V_in
Variables:
- V_out is the output voltage after attenuation (V)
- R is the resistance in the part of the circuit where voltage drop occurs (Ω)
- R_total is the total resistance of the circuit (Ω)
- V_in is the input voltage before attenuation (V)
To calculate the output voltage, divide the resistance where the voltage drop occurs by the total resistance of the circuit and multiply by the input voltage.
What is Voltage Attenuation?
Voltage attenuation refers to the reduction in voltage across a component or section of a circuit. It is a common phenomenon in electrical circuits, especially when dealing with resistors. Understanding voltage attenuation is crucial for designing circuits that require precise voltage levels at different points.
How to Calculate Voltage Attenuation?
The following steps outline how to calculate the Voltage Attenuation.
- First, determine the input voltage (V_in) in volts (V).
- Next, determine the resistance (R) in the part of the circuit where voltage drop occurs in ohms (Ω).
- Next, determine the total resistance of the circuit (R_total) in ohms (Ω).
- Next, gather the formula from above = V_out = (R / R_total) * V_in.
- Finally, calculate the output voltage (V_out) in volts (V).
- 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 (V_in) = 12 V
Resistance (R) = 600 Ω
Total resistance (R_total) = 1200 Ω
