Which of the following statements are true? Check all that apply. 1. In a circuit, current is delivered by the positive terminal of a battery, and it is used up by the time it returns to the negative terminal of the battery. 2. When an electric field is applied to a conductor, the free electrons move only in the direction opposite the applied electric field. 3. By convention, the direction of a current is taken to be the direction of flow for negative charges. 4. In order to maintain a steady flow of current in a conductor, a steady force must be maintained on the mobile charges. 5. Current is the total amount of charge that passes through a conductor's full cross section at any point per unit of time. I've been reading this chapter in my book over and over and I still can't figure this out. I'd really appreciate some help! Thanks.
