What does the symbol OHM represent in electrical terms?

The symbol OHM represents resistance in electrical terms. Ohm is the unit of measure for electrical resistance, named after the German physicist Georg Simon Ohm. It quantifies how much a material opposes the flow of electric current.

In terms of the relationship between voltage (measured in volts), current (measured in amperes), and resistance, Ohm's Law is fundamental. This law states that the current flowing through a conductor between two points is directly proportional to the voltage across those two points and inversely proportional to the resistance between them. The equation is often represented as V = IR, where V is voltage, I is current, and R is resistance.

Understanding resistance is crucial for various applications in electrical engineering and physics, as it impacts how circuits are designed and how effective they are in transmitting power.
