In the context of Ohm's Law, voltage is a fundamental concept that plays a crucial role in understanding and analyzing electrical circuits. It can be defined as the potential difference between two points in a circuit, which drives the flow of electrons. Voltage is commonly measured in volts (V) and can be visualized as the force that propels electrons along a conductor.

To comprehend voltage better, let's consider an analogy with a water circuit. Imagine a water pump that pushes water from one point to another in a closed loop. The pressure created by the pump represents the voltage in an electrical circuit, and the amount of water flowing represents the current. Just as a higher water pressure results in faster water flow, a higher voltage leads to a higher current in an electrical circuit.

Now, how do we measure voltage? We use a device called a voltmeter, which is connected across a component or along a specific path in the circuit. The voltmeter measures the potential difference between the two points and provides a numerical value in volts.
