❤️Definition: The anode of a device is the terminal where current flows in from outside. The cathode of a device is the terminal where current
flows out. This is illustrated in figure
◆◆◆◆◆◆◆◆◆
Figure : Anode and Cathode Currents
A useful mnemonic is ACID : Anode Current Into Device. By current we mean the positive conventional current. Since electrons are negatively charged, positive current flowing in is the same as electrons flowing out.
That’s essentially all there is to it.
