Motorcycle Electrical System Terms Glossary

Here in this informative piece, we will acquaint you with the basics of a modern two-wheeler’s electrical system.

VOLTAGE

In simple terms, Voltage is the pressure from an electrical circuit’s power source. This pressure pushes the charged electrons (termed as current) through the circuit, and makes it perform any specific work, like running a fan, or illuminating a bulb. This electric pressure is measured in volts (V).

The Voltage of a battery goes down when the battery is used and loses its charge. Similarly, when an electrical application draws power from the battery, the voltage goes down.

WATTAGE

Wattage is a unit of power, or in simple terms, of the rate at which energy is consumed. One watt is one joule (a unit of energy) consumed per second (1 W = 1 J/s). So for example, if a light bulb, rated 100W runs for 10 hours, it would have consumed 100W x 10 hours = 1000 Watt-hours = 1 kW-hour of energy. Fun Fact: KW-hour is the unit used for power consumption in our houses as well.

AMP-HOUR

A battery’s Amp Hour rating describes how long it will last while discharging at a fixed rate. For example, a 12 Amp-Hour battery can discharge 1.2-ampere current for 10 hours. If you double the current discharge to 2.4 ampere, the battery will discharge in half the time, or 5 hours, and so on. Can you imagine?
