Diode Positive Side

This is accomplished by joining one material for the negative side to another different material for the positive side. Thus the cathode is the negative side of the diode.

The positive side of the diode that is the lead attached to the p type semiconductor is called the anode.

Diode positive side. Diodes are simple semiconductors that allow current to flow only in one direction. The positive side is called the anode and the negative one is called the cathode. Knowing which side of an led or light emitting diode is the positive anode side and which side is the negative cathode side is essential if you want to make the led emit light.

If the diode is reversed the current is blocked up to a limit. The negative side of a diode is called the cathode and the positive side of the diode is called the anode. When a voltage source is connected to a diode such that the positive side of the voltage source is on the anode and the negative side is on the cathode.

Current through a diode can only flow from the anode to the cathode which would explain why its important for a diode to be connected in the correct direction. If the positive side of a voltage source is connected to the positive end of the diode the anode and the negative side is connected to the negative end of the diode the cathode the diode will conduct current. The diode circuit symbol with the anode and cathode marked.

The grey coating signifies the vertical line in. Hello as shown in the second image below the positive side of the diode is the one which is towards the left of the grey coating while the negative side is towards the right of the grey coating. For the led to emit light the voltage on the anode must be positive.
