Formula: Voltage Divider
Voltage divider - Circuit

Output voltage

Unit
Output voltage is the (desired) voltage you get between the two ends of the resistor \(R_2\).

Input voltage

Unit
Applied voltage to be reduced to the value \(U_{\text{out}}\) using the voltage divider.

Electrical resistance

Unit
One of the two resistors used to build the voltage divider. \(R_1\) must be selected appropriately to get the desired output voltage \(U_{\text{out}}\). The larger \(R_1\) is chosen, the smaller the output voltage will be.

Electrical resistance

Unit
Electrical resistance of the resistor at which the resulting voltage \(U_{\text{out}}\) is present.
