Wha one coulomb? calculate the nunber of electrons constituting one coulomb of charge. he electric potential. how much enerogy is given to each coulomb of charge passing through ae electric current. an electric bulbdrains a current of 0.25 a for 20 minutes. calculate the amohic charge that flows through the circohm's law. also define resistance, which factors, the resistance depends? sh a 6v battery? e amount ofa) state ohns) on which ta) a current ofcurrent of 200ma flows through a 452 resistor. what is the p. d. across the resistor?
