Voltage Attenuation Calculator

Formula

The formula to calculate the Output Voltage (V_out) is:

\[ V_{out} = \left( \frac{R}{R_{total}} \right) \times V_{in} \]

Where:

\(V_{out}\) 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)

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.

Example Calculation

Let's assume the following values:

Resistance where Voltage Drop Occurs (R) = 5 Ω
Total Resistance (R_total) = 10 Ω
Input Voltage (V_in) = 12 V

Using the formula to calculate the Output Voltage (V_out):

\[ V_{out} = \left( \frac{R}{R_{total}} \right) \times V_{in} = \left( \frac{5}{10} \right) \times 12 = 0.5 \times 12 = 6 \text{ V} \]

The Output Voltage (V_out) is 6 V.
