Potential Difference
Potential difference, also known as voltage, is a fundamental concept in physics and electrical engineering. It refers to the difference in electric potential between two points in an electric circuit.
Electric potential is a measure of the electric potential energy per unit charge at a given point in space. It is typically measured in volts (V). When there is a potential difference between two points in a circuit, it means that work can be done to move an electric charge from one point to another.
Potential difference is responsible for the flow of electric current in a circuit. It is related to the movement of charged particles, such as electrons, through a conductor. When a potential difference is applied across a conductor, the electric charges experience a force that drives them to move. The amount of current flowing through the circuit depends on the magnitude of the potential difference and the resistance of the circuit, according to Ohm’s law: V = I × R, where V is the potential difference, I is the electric current, and R is the resistance.
Potential difference plays a crucial role in various electrical devices and systems, including power generation, transmission, and utilization. It is used to power electronic devices, provide electrical energy to homes and industries, and perform work in electrical systems.
In summary, potential difference is the difference in electric potential between two points in an electric circuit, and it is essential for the flow of electric current and the functioning of electrical devices.

- Potential Difference: The battery creates a potential difference across its terminals, establishing an electric field within the circuit.
- Current Flow: The potential difference causes free electrons within the conducting wires to move. Electrons flow from the battery’s negative terminal through the circuit, including the light bulb, and back to the positive terminal.
- Resistance: The light bulb presents resistance to the flow of electrons due to its filament. This resistance restricts the current flow in the circuit.
- Potential Difference Distribution: As electrons pass through the light bulb’s filament, a potential difference is established across the bulb. This potential difference causes the filament to heat up and emit light.
