The product of emf current and time is
WebbCurrent electricity is defined as an electric charge in motion. Current flow consists of a flow of negative electron charges from atom to atom, as illustrated in Figure 1. Figure 1 … WebbThe induced emf produces a current that opposes the change in flux, because a change in flux means a change in energy. Energy can enter or leave, but not instantaneously. Lenz’s law is a consequence. As the change begins, the law says induction opposes and, thus, slows the change.
