Voltage Divider Calculator

Voltage divider wide variety cruncher: computes the voltage drops on every resistor load, while associated in collection.

Enter whole voltage supply and press the Calculate button:

Enter total voltage: VT = Volts [V]
Enter resistance of first load: R1 = Ohms [Ω]
Enter resistance of second load: R2 = Ohms [Ω]
Enter resistance of third load:

(optional)

R3 = Ohms [Ω]
       
Voltage drop of R1: V1 = Volts [V]
Voltage drop of R2: V2 = Volts [V]
Voltage drop of R3: V3 = Volts [V]

Voltage divider rule

For R1 and R2 in series and Vout is the voltage of R2:

In hardware, a voltage divider (in any other case called a probable divider) is a latent instantly circuit that creates a result voltage that may be a small a part of its comments voltage . Voltage department is the aftereffect of conveying the records voltage most of the elements of the divider. A straightforward example of a voltage divider is resistors related in series, with the data voltage carried out across the resistor pair and the end result voltage rising up out of the association among them. Resistor voltage dividers are usually used to make reference voltages, or to decrease the greatness of a voltage so it tends to be predicted, and might likewise be applied as sign attenuators at low frequencies. For direct present day and relatively low frequencies, a voltage divider might be effectively unique whenever made totally of resistors; wherein recurrence reaction over a extensive reach is needed, (as an instance, in an oscilloscope test), a voltage divider might have capacitive additives introduced to repay load capacitance. In electric powered electricity transmission, a capacitive voltage divider is utilized for estimation of excessive voltage.
