DC Voltage Drop Formula

DC Voltage Drop Formula

Physics is a basic discipline of science that deals with the study of matter’s behaviour. The primary objective is to comprehend how the cosmos operates and how energy is generated. Physics is one of the oldest branches of science that investigates matter and its mobility and diverse behaviours through space and time, as well as the associated entities. Learn Physics in depth with Extramarks and go further into topics such as Mechanics, Optics, Thermodynamics, Electromagnetism, and Relativity, among others.

The Dc Voltage Drop Formula is used to compute voltage drop in an electrical circuit. Voltage drop is the reduction in electric potential when current flows through the circuit. Impedance causes a drop in voltage in the circuit.

The Dc Voltage Drop Formula is as follows

The Dc Voltage Drop Formula V=IR


The voltage drop in the circuit is the V

The current through the circuit is the I

The resistance is the R

Direct Current

Direct Current (DC) is characterised by the unidirectional passage of electric charge. DC is generated by electrochemical cells and batteries. The DC can be carried across the vacuum via wires, semiconductors, electrons, or ion beams. Unlike alternating current, DC current flows in just one direction (AC). DC was previously known as Galvanic Current. AC and DC are abbreviations for Alternating Current and Direct Current, respectively.

To enable current to flow in just one direction, a rectifier made up of electrical or electromechanical parts can be utilised. This can aid in the conversion of direct current to alternating current. Inverters are devices that convert direct current to alternating current.

Direct current can be used to charge batteries and provide enormous quantities of power to electronic devices, drive motors, and so on. Electrochemical activities such as aluminium smelting, for example, may be carried out using vast amounts of power supplied by direct current. Direct current is also used in the functioning of some urban trains. Direct current can transport large volumes of electricity with high voltage to alternating power networks.

Because batteries and solar power systems can only produce DC, they are used in extra-low voltage or low-voltage applications. A DC power source is required by the majority of electronic circuits.

Direct Current Voltage Drop Formula

The voltage drop over an electrical circuit may be calculated using the Voltage Drop Formula. It describes the energy loss caused by the resistance to the flowing current in the circuit.

The Dc Voltage Drop Formula  is given below,

The Dc Voltage Drop Formula  V=L× IT

Current through the circuit in Amperes is the V

Length of the circuit in metres is the L

Time for which the current has flowed through the circuit in seconds is T

Voltage in Volts is V
