Ventricular fibrillation is one type of arrhythmia that can be deadly. It occurs when the heart beats with rapid, erratic electrical impulses. This causes pumping chambers in your heart (the ventricles) to quiver uselessly instead of pumping blood.
A VOLTAGE REGULATOR regulates the charging voltage that the alternator produces, keeping it between 13.5 and 14.5 volts to protect the electrical components throughout the vehicle. There is also a system to warn the driver if something is not right with the charging system.
voltage regulator - a transformer whose voltage ratio of transformation can be adjusted. 1  electrical system - equipment in a motor vehicle that provides electricity to start the engine and ignite the fuel and operate the lights and windshield wiper and heater and air conditioner and radio. transformer - an electrical device by which alternating current of one voltage is changed to another voltage.
