Key Concepts

Ohm's Law

Ohm's Law is a foundational principle in electrical circuits that establishes the relationship between current, voltage, and resistance. It states that the current flowing through a circuit is directly proportional to the voltage applied and inversely proportional to the resistance present. This relationship, expressed as I = V/R, helps in understanding how changes in voltage or resistance affect the current in a circuit.

Voltage

Voltage, or electric potential difference, is the force that pushes electric charges through a conductor. Increasing the voltage in a circuit provides a greater force to drive more current through the same resistance, making it one method to increase the current. It serves as the energy source for moving charges through the circuit.

Resistance

Resistance is a measure of how much a material or component opposes the flow of electric current. Lowering the resistance in a circuit reduces the opposition to the movement of charge, thereby allowing more current to flow for a given voltage. Adjusting resistance is an effective way to control and increase the current in an electrical circuit.
