The term 'cathode's counterpart' is referring to the ANODE, which is a 5-letter word. An ANODE is an electrode that is positively charged and attracts negatively charged particles, such as electrons. It is the opposite of a cathode, which is negatively charged and repels positively charged particles. In a circuit, the ANODE is the terminal where current flows in, while the cathode is the terminal where current flows out.
