8.6 Hanyar Gudanarwa (Drive Method)

An LED is a current-operated device. In order to ensure intensity uniformity on multiple LEDs connected in parallel in an application, it is strongly recommended that a current limiting resistor be incorporated in the drive circuit, in series with each LED. Driving LEDs directly from a voltage source without a series resistor (connecting multiple LEDs in parallel) is not recommended, as the brightness of each LED might appear different due to the natural variations in the forward voltage (I-V) characteristics of individual LEDs. The series resistor stabilizes the current through each LED, ensuring consistent brightness and protecting the LED from current spikes.
