Mission EC4 Resistance, Voltage and Current
Mission EC4 focuses on the conceptual and mathematical relationship between resistance, voltage and 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 identify the definition of resistance, the units of resistance, and the factors effecting the amount of resistance in a circuit.
- The student should be able to predict the effect of varying voltage and resistance upon the current in a circuit and upon the brightness of a light bulb.
