Which is positive on a LED?
LED polarity
LEDs are diodes which are elecronic devices that only allow current to go through them in one direction. …
The voltage supply side of the diode
is the positive (+) side, this is called the anode. The negative side is called the cathode.
Which way do you put an LED?
If you choose to fit horizontally, it's best to
stick the LED as close as possible behind the lip of the drop-ceiling
, in order to avoid light-dots shining on the vertical surface behind.
How is LED light pronounced?

What should be the biasing of LED?
5. What should be the biasing of the LED? Explanation: The LED works when
the p-n junction is forward biased
i.e., the p- side is connected to the positive terminal and n-side to the negative terminal.
How do you tell the positive and negative terminal of an LED?
Turn the multimeter to the diode setting (usually indicated by a diode symbol), and touch each probe to one of the LED terminals. If the LED lights up,
the positive probe is touching the anode
, and the negative probe is touching the cathode.
Where do you connect the positive terminal of LED?
A simple LED circuit is arranged such that the positive terminal of the battery is connected
through a resistor to the anode of the LED
. The LED's cathode is connected to the negative terminal of the battery.
How do I know what LED to get?
To test your LED,
touch the tip of the black probe to the cathode
, or shorter end of the LED. Touch the tip of the red probe to the anode, which should be the longer end. Be sure that the two probes do not touch each other during this test, and that the cathode and anode do not touch each other.

Is zener a diode?
A Zener diode is
a silicon semiconductor device that permits current to flow in
either a forward or reverse direction. The diode consists of a special, heavily doped p-n junction, designed to conduct in the reverse direction when a certain specified voltage is reached.
