## Voltage Divider and Current Divider

In electronics , a current divider is a simple linear circuit that produces an output current I X that is a fraction of its input current I T. Current division refers to the splitting of current between the branches of the divider. The currents in the various branches of such a circuit will always divide in such a way as to minimize the total energy expended. The formula describing a current divider is similar in form to that for the voltage divider. However, the ratio describing current division places the impedance of the considered branches in the denominator , unlike voltage division where the considered impedance is in the numerator.

Voltage Divider and Current Divider are the most common rules applied in practical electronics. As you know, there are two types of combinations in a circuit, they are series and parallel connections. Parallel circuits are also known as current divider circuits because, in these circuits, the current is divided through each resistor. Whereas, series circuits are known as voltage divider circuits because here voltage is divided across all the resistors. Voltage division rule and current division rule are necessary to understand voltage and the current flowing through each resistor. These division rules are used in most common electronic devices. In order to send a current through an electric conductor , an electromotive force has to be applied.

In electronics , a voltage divider also known as a potential divider is a passive linear circuit that produces an output voltage V out that is a fraction of its input voltage V in. Voltage division is the result of distributing the input voltage among the components of the divider. A simple example of a voltage divider is two resistors connected in series , with the input voltage applied across the resistor pair and the output voltage emerging from the connection between them. Resistor voltage dividers are commonly used to create reference voltages, or to reduce the magnitude of a voltage so it can be measured, and may also be used as signal attenuators at low frequencies. For direct current and relatively low frequencies, a voltage divider may be sufficiently accurate if made only of resistors; where frequency response over a wide range is required such as in an oscilloscope probe , a voltage divider may have capacitive elements added to compensate load capacitance.

A parallel circuit is often called a current divider for its ability to proportion—or divide—the total current into fractional parts. Knowing that branch currents add up in parallel circuits to equal the total current, we can arrive at total current by summing 6 mA, 2 mA, and 3 mA:. The final step, of course, is to figure total resistance. Once again, it should be apparent that the current through each resistor is related to its resistance, given that the voltage across all resistors is the same. Rather than being directly proportional, the relationship here is one of inverse proportion.

In electronics, the voltage divider rule is a simple and most important electronic circuit , which is used to change a large voltage into a small voltage. The best example for a voltage divider is two resistors are connected in series. Generally, these dividers are used to reduce the magnitude of the voltage or to create reference voltage and also used at low frequencies as a signal attenuator. For DC and relatively low frequencies, a voltage divider may be appropriately perfect if made only of resistors; where the frequency response is required over a wide range. Definition: In the field of electronics, a voltage divider is a basic circuit, used to generate a part of its input voltage like an output.

Voltage Divider Rule VDR shows how the voltage distributes among different resistors in a series circuit. Each resistor in series combination has a different voltage drop across it. The individual voltage drop of resistors adds up to source voltage. While the current for the series circuit remains the same throughout the divider circuit as discussed earlier.
