OHM is a unit that measures what in an electrical circuit?

OHM is a unit that measures electrical resistance in an electrical circuit. Resistance is a key concept in understanding how electricity flows through a circuit, as it quantifies how much a component or material opposes the flow of electric current. According to Ohm's Law, which is fundamental in electrical theory, the relationship between voltage (electrical pressure), current (electrical flow), and resistance is defined by the formula: Voltage = Current x Resistance. Thus, when we refer to OHMs, we are specifically discussing how much resistance there is to the flow of electric current, helping to determine how effectively an electrical circuit can operate. This concept is essential for fire inspection practices, as proper functioning of electrical systems is critical in preventing fire hazards caused by electrical failures.
