Mission EC10: Parallel Circuit Calculations

Mission EC10 pertains to the mathematical analysis of parallel circuits. Given the battery voltage and resistance values, you should be able to calculate the current in and voltage drop across all resistors. The mission consists of 20 questions organized into 5 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 mathematically analyze a parallel circuit to determine the equivalent resistance, the total circuit current, the voltage drop across each resistor, and the current through each branch (if given the battery voltage and the resistance of each resistor).
