Qᴜᴇꜱᴛɪᴏɴ :
What is the current through the led?
ᴀɴꜱᴡᴇʀ :
The LED current must be less than the maximum permitted for your LED. For standard 5mm diameter LEDs the maximum current is usually 20mA, so 10mA or 15mA are suitable values for many circuits. The current must be in amps (A) for the calculation, to convert from mA to A divide the current in mA by 1000.
HOPE IT HELPS YOU DEAR ✌️✌️
