WebbWith LED's it is the diode junction's physical construction that determines the plus (Anode) and negative (Cathode) of the device. The lead's length is used by the manufacturer to alert the person handling the device during an assembly process what wire of the device is the Anode (positive lead) and which is the Cathode (negative lead). Webb4 okt. 2024 · This stripe indicates the cathode, or negative, side of the diode. The other way to identify polarity is to use a multimeter. When testing a diode with a multimeter, you’ll need to connect the leads to the two different sides of the diode. The positive lead should be connected to the anode, or positive, side of the diode.

In a perfectly ideal diode, current flows in one direction only, from the anode (positive side) to the cathode (negative side) which is marked with the stripe.

WebbA rectifier (diode) has two terminals, a cathode and an anode as shown. If a negative voltage is applied to the cathode and a positive to the anode the diode is said to be forward biased and it will conduct. If it is reverse biased it will not conduct. So a diode will only conduct current in one direction ie. from cathode to anode.
