Voltage Divider Calculator
A Voltage Divider is a linear circuit that is utilized to divide a given supply voltage across multiple component paths in series. This calculator is made to calculate the Output Voltage across two given Resistors.
Voltage Divider Diagram:
Calculation Parameters:
- Source Voltage [\(V_s\)]: The input voltage to the voltage divider circuit.
- Resistor 1 [\(R_1\)]: The resistance of the 1st resistor in ohm.
- Resistor 2 [\(R_2\)]: The resistance of the 2nd resistor in ohm.
How do you calculate the output voltage?
The output voltage can be calculated using the following formula:
\[V_{out} = V_{in} \cdot \frac{R_2}{R_1 + R_2}\]Example Calculation:
Let's assume we have a voltage divider circuit with a source voltage (\(V_s\)) of 12V, resistor \(R_1\) of 10kΩ, and resistor \(R_2\) of 5kΩ. Using the voltage divider formula, we can calculate the output voltage (\(V_{out}\)) as follows:
\[V_{out} = V_{s} \times \frac{R_{2}}{R_{1} + R_{2}}\]Substituting the values, we get:
\[V_{out} = 12V \times \frac{5000\Omega}{10000\Omega + 5000\Omega} = 4V\]Therefore, the output voltage (\(V_{out}\)) is 4V.
