Mission EC2: Voltage

Mission EC2 pertains to the concept of electric voltage. You should know its meaning, the units of measurement, and the fundmental characteristics of electric voltage. The mission consists of 32 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 identify the definition of voltage, the units of voltage, and relate voltage to the electric potential difference between two points on a circuit.
• The student should be able to recognize the role of a battery as a charge pump which establishes an electric potential difference across its terminals so that charge can spontaneously flow through the external circuit.
