The polarity markings on LEDs (Light Emitting Diodes) seem to be a common cause of confusion. The polarity may be indicated by a flat section on one side of the body or by one lead being shorter than ...

The resistance of the diode cannot be measured with the normal ohmmeter on a DMM because the voltage used may not be high enough to bias the diode. DMM’s often have a diode testing mode that supplies ...

This file type includes high resolution graphics and schematics. LEDs are the most efficient way to turn an electric current into illumination. When a current flows through a diode in the forward ...

Light Emitting Diode (LED) lighting has been gaining popularity in the wheeling world. Although still fairly expensive when compared to other technologies, LEDs offer a host of benefits that make them ...
