[ ăn′ōd′ ]
The positive electrode in an electrolytic cell, toward which negatively charged particles are attracted. The anode has a positive charge because it is connected to the positively charged end of an external power supply.
The positively charged element of an electrical device, such as a vacuum tube or a diode, to which electrons are attracted.
The negative electrode of a voltaic cell, such as a battery. The anode gets its negative charge from the chemical reaction that happens inside the battery, not from an external source. Compare cathode.
