Solve problems involving percentage, ratio, and proportion.

Solution should include calculating percentage (e.g., conductor/box fill) and ratio and proportion (e.g., transformer windings), according to instructor’s guidelines.

Process/Skill Questions:

• What is the relationship between true power and apparent power?
• What is the ratio of a transformer with a 600 volt (V) primary and 120 V secondary?
• What percentage of a circuit can be used?
