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.
When a steady, reliable voltage is needed, voltage regulators are the go-to components. Voltage regulators take an input voltage and create a regulated output voltage regardless of the input voltage at either a fixed voltage level or and adjustable voltage level (by selecting the right external components).
