In the equation V = IR, what does V represent?

In the equation V = IR, V represents voltage, measured in volts. This equation is known as Ohm's Law, which establishes the relationship between voltage, current, and resistance in an electrical circuit. In this context, voltage is the electrical potential that drives the flow of electrons through a conductor.

Voltage can be thought of as the force that pushes electrical current through the circuit, while current is the flow of electricity and resistance is the opposition to that flow. Understanding that V signifies voltage is crucial for analyzing and solving problems related to electrical circuits, as it helps in determining how much electrical energy is required to move a given current through a particular resistance.
