Prevent Electrical Fires

Only you can prevent electrical fires (as the paraphrased saying goes), and fuses are an essential form of prevention.

In any electrical system, it’s important to protect against miswiring that can result in device damage or even fires. This hack explains voltage, amperage, and power levels, and points out several of the safety features (i.e., fuses) of your automobile’s electrical distribution system.

Amps

“Understand Car Electrical Systems” [Hack #1] defined voltage as the amount of potential or pressure behind electrical flow, and gave the analogy of a high- or low-pressure hose. To explain current in terms of water, we would be considering how many gallons of water went through the hose per hour. A very unscientific conceptual definition of electrical current (measured in Amperes, or amps —not to be confused with sound amplifiers!) is simply how many gallons of electrons pass through the wire per hour.
