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.
Best Answer: a voltage regulator inside the device or transformer in the power supply regulates the charging voltage to the same voltage. The device will charge at the same rate. The transformer will probably get warmer at 220 versus 110. for very simple devices, like maybe an electric shaver, both the voltage and cycles (50 or 60) must be considered.
