In automotive electrical circuits, a resistor is anything that presents a load to the power source by consuming current. The starter motor, when activated, becomes a very large electrical load because it draws a huge current from the battery to turn the engine. Even though it’s a motor, it can be described as a resistor in a broad sense because it resists current flow and converts electrical energy into mechanical energy. Its current draw is governed by the winding resistance and the back-EMF that develops as it spins, so its effective resistance changes during operation. The battery and alternator are energy sources, not resistors, and while a headlight is also a load (and can be modeled as a resistor in simple terms), the starter exemplifies the heavy-load component whose presence makes that broad-resistor idea useful in circuit analysis.
