Ohms are a unit of electrical resistance, which measures how much a material resists the flow of electric current. In an EV, resistance affects the efficiency of power delivery from the battery to the motor. Higher resistance leads to energy losses in the form of heat, which can reduce the vehicle’s range and charging speed. Ohm’s Law (V = IR) describes the relationship between voltage, current, and resistance, and is a fundamental principle in the design of EV electrical systems.
