Question

what are the functions of cathode and anode in a circuit? explain your answer..

Answer 1

cathode))))An anode is the electrode in a polarized electrical device through which current flows in from an outsidecircuit. Conversely, a cathode is the eletrode in a polarized electrical device through which current flows out.
anode))))))The basic function of the cathode is to expel the electrons from the electrical circuit and focus them into a well-defined beam aimed at the anode. The typical cathode consists of a small coil of wire (a filament) recessed within a cup-shaped region
