QuestionAnswer
what causes electricity jumping electrons
what is the movement of electricity current
what are the two types of current direct current and alternating current
what is alternating current when the generator switches charges and makes the electrons go back and forth
what is direct current when there is a circuit and the electrons flow from negative to positive
