Voltage divider

A voltage divider is a simple circuit which turns a large voltage into a smaller one. Using just two series resistors and an input voltage, we can create an output voltage that is a fraction of the input. Voltage dividers are one of the most fundamental circuits in electronics. Discuss Tutorial: Voltage. A simple example of a voltage divider is two resistors connected in series, with the input . Enter any three known values and press Calculate to solve for the other.

Benzer Bu sayfanın çevirisini yap Try our easy to use Voltage Divider Calculator. The two resistor voltage divider is one of the most common and useful circuits used by engineers. 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. This calculator helps determine the output voltage of the divider circuit given the input (or source ) . The output voltage is a fixed fraction of the input voltage.

The ratio is determined by two resistors. The divide-down ratio is determined by two resistors. Written by Willy McAllister. In application the output voltage depends upon the resistance of the load it drives. But just like resistors, a capacitive voltage divider network is not affected by changes in the supply frequency even though they use capacitors which are reactive elements as each capacitor in the series chain is affected equally by changes in frequency.

But before we can look at a capacitive voltage divider circuit in more . This video shows the basics of voltages dividers and how to build one. Power consumption considerations and. Introduces the voltage divider , which can be used to compute the voltage across one of two or more series. In this article, volatge devision rule with examples and applications. Different sets of resistor values may lead to the same identical lowest error.

Up to sets of resistors may be presente or as few as one. More than sets of resistors may . The supply voltage is divided between the two resistances to give an output voltage Vo which is the voltage across R2. An important use of voltage dividers is to connect input transducers to circuits.

Figure shows a simple voltage divider using fixed resistors to illustrate its functionality. For this illustration, we assume that the resistors are connected in series, and all current flowing out of . In many circuits, it is necessary to obtain a voltage not available from the main power source. Rather than have multiple power sources for all needed voltages , we can derive other voltages from the main power source. In most cases, the needed voltage is less than the voltage from the main source, so we can use resistors .
