What is 'anode' πŸ§‘β€πŸ”§


After a few coworkers requested my assistance on the matter, I decided to write about "What is 'anode'". If you're still with doubts, bear with me…

Is this definition ok for you?

An anode is the electrode in a polarized electrical device through which current flows in from an outside circuit. Conversely, a cathode is the electrode in a polarized electrical device through which current flows out.

And the quick answer is…

The terminal at which current enters a primary cell or storage battery; it is positive with respect to the device, and negative with respect to the external circuit. Also: The collector of electrons in an electron tube. Also: In a semiconductor diode, the terminal toward which forward current flows from the external circuit.

An anode is an electrode through which conventional current (positive charge) flows into the device from an external circuit, while a cathode is an electrode through which conventional current flows out of the device.

The direction of conventional current in a circuit is opposite to the direction of electron flow, so electrons flow out the anode of a galvanic cell, into an outside or external circuit connected to the cell.

I have selected a few questions and answers to help you understand it:

Anode

What is the mnemonic for anode current...

A common mnemonic is ACID for "anode current into device". The direction of conventional current (the flow of positive charges) in a circuit is opposite to the direction of electron flow, so (negatively charged) electrons flow out the anode into the outside circuit.

Thanks for reading up to this point and I hope you have great day.

Note to self: Draft for a new post.
