Mission EC3: Voltage, Power and Energy

Mission EC3 focuses on the conceptual and mathematical relationships between the voltage, electrical energy, and electrical power. The mission consists of 35 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 units of work (and energy), of power and of voltage and be able express an understanding of the meaning of such concepts.
• The student should be able to solve simple computational problems which focus on the relationship between work (and energy), voltage, and charge.
