What is LED? Why it
We may use a LED in place of electric bulb. LED glows even when a small electric current flows through it. There are two wires (called leads) attached to LED. One lead is slightly longer than the other one. Remember that while connecting a circuit the longer lead of LED is always connected to the positive of the battery and the shorter lead is connected to the negative terminal of battery.
