- \n
- In the Circuit A there is no resistance connected in series to the LED which causes the flow of current up to 35.93A which is far more the required current for an LED to operate. Hence, the LED blows.<\/li>\n
- In the Circuit B there is a resistance of 11 \u03a9 connected in series to the LED. In this condition there is the current of 0.051A flows through the LED which is more than the maximum of 0.02A which causes the LED to blow.<\/li>\n
- In the Circuit C there is the resistance of 22\u00a0\u03a9 is connected in series to the LED. In this condition there is a current of 0.019A flows through the LED. Since the current is below 0.02A the LED is intact and works fine.<\/li>\n<\/ul>\n
LED Color and its Corresponding Threshold Voltages<\/h2>\n
<\/p>\n
With a recent update in the DCACLAB a feature in LED was introduced in which you select the color of the LED and its corresponding threshold voltage takes into effect.<\/p>\n
Below is the list of the color and its\u00a0threshold or forward voltage which you will find while switching the colors of the LED.<\/p>\n
