Name ____________________ Date ______ Mr. Carcich CP Physics Current Electricity & Circuit Review Be sure you understand completely the following concepts. You need to know: Electric Current Define current. What are the units for electrical current? What is conventional current? What is drift velocity? Current- the rate of flow of electrical charges Conventional current- the flow that positive charges would flow (if they did flow), positive to negative Actual current- direction that electrons would flow, negative to positive Drift velocity- average velocity that a particle, such as an electron, attains due to an electric field What is necessary for a current to begin to flow? What must you connect to a circuit?
