An anode's an electrode through which electric current flows into a polarized electrical device. Mnemonic: ACID (Anode Current Into Device). Electrons flow in the opposite direction to the electric current (flow of hypothetical positive charge) A widespread misconception's that anode polarity's always positive. This's often incorrectly inferred from the correct fact that in all electrochemical devices negatively charged anions move towards the anode (whence their name) and/or positively charged… (More on Anode)
