The discussion clarifies the roles of positive and negative electrodes in electrical systems, specifically defining the positive electrode as the anode and the negative electrode as the cathode. The voltage reading is determined by the potential difference, calculated as the charge of the positive electrode minus the charge of the negative electrode. This potential difference reflects the energy available per charge, which is influenced by the wiring configuration of the electrodes.
PREREQUISITESStudents in electrical engineering, educators teaching basic physics, and professionals involved in circuit design or electrochemistry.
The voltage is the difference of the electromagnetic potential between the electrodes. The difference of available charges if you like or more precisely energy per charge. Whether this is positive or negative depends on how you wired them. The positive electrode (anode) attracts electrons and the negative electrode (cathode) releases them.Kuzon said:I'm so confused, is the voltage reading of the meter gathered by:
positive electrode charge - negative electrode charge = potential difference
I don't get why there is a positive and negative electrode and what they do
