Define Voltage? - correct answer -The driving force that makes current flow in a circuit. Voltage often represented by the letter E, is also referred to as electromotive force (emf), difference of potential, or electrical pressure. Define Current? - correct answer -The movement, or flow, of electrons in a circuit. Current(I) is measured in amperes. Define Resistance? - correct answer -An electrical property that opposes the flow of current through a circuit. Resistance (R) is measured in o...
