One of the most basic and common circuits is the two resistor voltage divider. Voltage dividers are used to make signal level adjustments, for active device and. Voltage divider calculator shareware, freeware, demos. The ratio of the resistors divides and input voltage down to a lower voltage. The voltage divider is a circuit used to create a voltage less than or equal to the input voltage. System sensor voltage drop calculator for mac os x by system sensor, voltage drop calculator by mc group inc, system sensor voltage drop calculator by systemsensorcom etc. Inputs voltage input vin volts v resistance 1 r1 ohms. Just enter 2 known values and the calculator will solve for the others. Voltage divider calculator calculates the voltage drops on each resistor load, when connected in series. The two resistor voltage divider is one of the most common and useful circuits used by engineers. Voltage divider calculator software free downloads. A voltage divider is a passive linear circuit that produces an output voltage vout that is a fraction of its input voltage v1.
The supply voltage is divided between the two resistances to give an output voltage v out which is the voltage across r b. Enter total voltage supply and press the calculate button. This calculator helps determine the output voltage of the divider circuit given the input or source voltage and the. Resistor voltage divider calculator free downloads and. Use this tool to calculate the output voltage of a resistor divider circuit for a given set of resistor values and source voltage. A voltage divider circuit is a very common circuit that takes a higher voltage and converts it to a lower one by using a pair of resistors. Free voltage divider calculator to download at shareware. The primary purpose of this circuit is to scale down the input voltage to a lower value based on the ratio of the two resistors. For a dc circuit with constant voltage source v t and resistors in series, the voltage drop v i in resistor r i is given by the formula.
