both figures show a current to the right?
Explain.
The rate of flow of electric charge is more commonly called electric current. If charge AQ flows through a AQ conductor in time At, then the I = current can be expressed At mathematically by the relationship The SI unit of current is called the ampere (A). One ampere represents the flow of one coulomb of charge through a conductor in a time interval of...
