## What is Voltage Divider Calculator ?

The circuit in the form of a voltage divider is one of the simplest tools that can be employed in many applications to split a voltage into smaller parts. It is, in essence, a basic delineation of an electronic circuit with two resistors in parallel connection.

The voltage divider find a prominence in regular and special applications in microelectronics, for instance in regulation/shifting of level/conditioning of signal. It is also one of measuring emissions across the circuit or component’s polarity. Voltage divider is one of the necessary circuits that can be applied because of its flexibility, cheapness, and a very simple and easy process of implementation. The voltage divider calculator is an online tool that helps to calculate the output voltage of a voltage divider circuit. It is a very helpful tool for engineers and hobbyists who work with electronics. The calculator takes input values such as the input voltage, the resistance values of the resistors, and the output voltage. It then calculates the output voltage of the voltage divider circuit.

## What is Voltage Divider ?

A voltage divider is an electrical circuit that divides a voltage into two or more components. It is a simple circuit that is commonly used in electronics to provide a lower voltage from a higher voltage source. The basic principle of a voltage divider is based on Ohm’s law, which states that the current flowing through a resistor is proportional to the voltage across it. A voltage divider consists of two resistors in series connected across a voltage source. The voltage across each resistor is proportional to its resistance, and the sum of the voltages across the two resistors is equal to the total voltage across the circuit.The output voltage is tapped in between the two resistors. The ratio of the two resistors specifies the power of divider in the yoke. If the two resistors are inscribed with the same values, the output voltage will be yielded as half the input voltage. In case the two resistors have twice the value of each other, the output voltage will be just one-third of the input voltage. Often, these are used in voltage regulation like a simple circuit to more complex circuits. They are typically seen in switching mode power supplies, audio amplifiers, and digital circuits where they are employed for reliable reference voltage. Not only are they deployed for the positioning of a voltage with the reference to the input voltage, but they are also used as sensors, for example, in light-sensitive elements and temperature-sensitive elements. Among the most significant benefits associated with the voltage divider is their easiness and low cost. They have an easy construction from several resistors and are capable to output a precision that is accurate. These have also proved to be very versatile and can be used from time to time. On the other hand, the voltage dividers suffer from certain weaknesses. The most crucial drawback that they carry is a high susceptibility to the voltage changes of input and load resistance. Under any circumstances, modification of the working voltage or output resistance will result in a disturbance of the output voltage and the accuracy of the circuit. Furthermore, voltage dividers can consume a lot of power that is usually proportional to heating within the circuit as a result of it destroying effectiveness of the circuit.

### Formula of Voltage Divider :

The output voltage can be calculated using the following formula: Vout = Vin x (R2 / (R1 + R2))

Where Vin is the input voltage, R1 is the resistance of the first resistor, R2 is the resistance of the second resistor, and Vout is the output voltage.
