noun
An anode is a piece of metal that protects other metal from corrosion by attracting the corrosion to itself. It is commonly used in boats or underwater structures.
An anode rod is used in water heaters to prevent corrosion of the water tank.
Often appears as...

Pro Tip 1/2Polarity Reminder
Always remember that 'anode' is the positive terminal, opposite of 'cathode', which is negative.
Connect the red wire to the anode of the battery.
Pro Tip 2/2Current Direction
'Anode' is where current flows into a device, not out.
The technician marked the anode where the current enters the circuit.

Reverse Electroplating PIPE...
I'm psyched there's a whole bunch of gold pins here this ultimately could be a couple thousand dollars I won't know for sure though until I get all the gold off using chemicals and electricity the way this works is we're gonna use a bar OLED this is what's called the anode I'm
Video examples
How transistors work -...
If the anode is at a slightly higher positive potential, the electrons are attracted to it, completing the circuit. This unidirectional current flow could be controlled by varying the voltage to the cathode, which makes it release more or less electrons.

basically what's happening in a fuel cell, in the anode of a fuel cell and in a reversible fuel cell. In our fuel cells, we do it with platinum; life does it with a very, very common iron.
