Voltage Divider Calculator Voltage Divider Calculator Voltage Divider Calculator Input Voltage (\(V_{in}\)) in Volts (V) Resistor 1 (\(R_1\)) in Ohms (Ω) Resistor 2 (\(R_2\)) in Ohms (Ω) Calculate Understanding Voltage Dividers A voltage divider is a simple circuit that converts a higher voltage into a lower one using two resistors in series. The output voltage is a fraction of the input voltage, determined by the ratio of the two resistors. The formula for the output voltage in a voltage divider is: \[ V_{out} = V_{in} \times \frac{R_2}{R_1 + R_2} \] Where: \(V_{in}\) is the input voltage (V) \(V_{out}\) is the output voltage (V) \(R_1\) is the resistance of the first resistor (Ω) \(R_2\) is the resistance of the second resistor (Ω) Example Calculation For an input voltage of 12V, with \(R_1 = 10k\Omega\) and \(R_2 = 5k\Omega\): \[ V_{out} = 12 \times \frac{5000}{10000 + 5000} = 4V \] Use the calculator above to experiment with different resistor values to see how they affect the output voltage!
