Mission EC1 Current
Mission EC1 pertains to the concepts of an electric current. You must know the units, the meaning, and the fundamental characteristics of electric current. The mission consists of 37 questions organized into 10 Question Groups. You must answer one question from each Question Group to complete the mission. The learning outcomes for this mission are ...
Learning Outcomes
- The student should be able to recognize current as the rate at which charge flows past a point, identify the units for electric current, and perform simple computations regarding electric current.
- The student should be able to identify the conditions which are necessary for an electric current to be established within a circuit and recognize that the current is the same everywhere within the circuit.
