FCC Technician Exam Question Of The Day (T6C05)
Q) What is component 4 in figure T1?
A battery stores energy. It is made of one or more electrochemical cells that convert stored chemical energy into electrical energy. Each cell contains a positive terminal (cathode) and a negative terminal (anode). Electrolytes allow ions to move between the electrodes and terminals, which allows current to flow out of the battery to perform work (e.g. powering your ham radio).
