👉 Voltaic energy is a type of electrical energy that occurs when an electric current flows through a conductor, such as a metal wire or a capacitor. This process can be described using the formula E = IR, where E is the electromotive force (EMF), I is the current flowing in the conductor, and R is the resistance of the conductor. In this equation, E represents the total energy that flows through the circuit, while I represents the amount of current flowing. The EMF is
