Mnemonic: ACID (Anode Current Into Device). In that selected portion's counterpart, or outer-portion of the path, current flows from Anode(of the selected part, here diode) to Cathode ( of the selected part, here diode). An anode is an electrode through which (positive) electric current flows into a polarized electrical device. Within the circuit's portion of interest (Here it is diode), Current flows in its Anode to Cathode direction. Red Cat stands for reduction is at the cathode. It is applicable for any-components like Electrochemical (Battery)-Cell,, Electrolytic-cell, Cathode-ray-Tube( CRT), etc.Ĭircuit's portion-of-interest(here diode)'s Anode is to be attached with circuit- counterpart(here battery)'s Cathode.Īnd Circuit's portion-of-interest(here diode)'s Cathode to be attached with circuit's Counterpart(here battery)'s Anode. Explanation: A good mnemonic to memorize for the electrochemistry chapter is : Red Cat and An Ox. A selected portion of Circuit portion(portion of interest)(here diode)'s Cathode is the electrode that Vomits out-out positive-charge Īnd the circuit's portion-of-interest(here diode)'s Anode is the electrode that Sucks-in the positive charge.Ībove-table: Anode-Cathode Vs Plus-Minus Disambiguation The direction of conventional current in a circuit is opposite to the direction of electron flow, so electrons. A common mnemonic is ACID, for 'anode current into device'. This contrasts with a cathode, an electrode of the device through which conventional current leaves the device. That tells the direction of allowed-direction of current.įrom the second-method, we-can easily remember, the direction of current.Īnd ow. An anode is an electrode of a polarized electrical device through which conventional current enters the device. The triangle inside the diode, makes an arrow sign.Now, if once we learn to recognize the K, if the diode orientate to a different direction in the diagram, we could easily identify the anode and cathode. However, the rule is as follows: in a device which consumes power the anode is positive and in a device which provides power the anode is negative. I am not aware of any mnemonic for charge.
The mnemonic for galvanic cells is correct. A mnemonic device (/ n m n k / nih-MON-ik), or memory device, is any learning technique that aids information retention or retrieval (remembering) in the human memory for better understanding. Id like to know if there is a mnemonic for the charge of anode and cathode.
Now, the side of diode, where K was drawn, is Cathode (K).īy default, the opposite side is anode (A). Knuckle mnemonic for the number of days in each month of the Gregorian Calendar.Each knuckle represents a 31-day month. Now, just fill in the blanks to make it a diode. We can easily remember, anode is abbreviated as A, and Cathode as K.Both technique I've learnt from someone else, many-years ago.
