Below are sample questions representative of the exercises included on this worksheet and related 9.86 Electrical Energy and Power skill assessments:

Problem 1Difficulty: Mastery

An emergency beacon must provide at least 24 Wh of useful light using no more than 40 Wh of battery energy. Which option meets the goal with the least battery energy?

AOption A: 40 Wh input and 28 Wh useful light

BOption B: 35 Wh input and 21 Wh useful light

COption C: 30 Wh input and 24 Wh useful light

DOption D: 45 Wh input and 30 Wh useful light

Solution & Explanation:The option must meet at least 24 Wh useful output and use no more than 40 Wh input. A and C meet both, and C uses less battery energy. B lacks enough useful light, and D exceeds the input limit.

Problem 2Difficulty: Mastery

A phone battery receives 54 Wh of stored energy from a charger system that is 90 percent efficient. The charger input power is 18 W. About how long must the charger run?

A4.9 h

B3.3 h

C10.8 h

D2.7 h

Solution & Explanation:The input energy must be 54 Wh / 0.90 = 60 Wh. Time = 60 Wh / 18 W = about 3.3 h.

Problem 3Difficulty: Mastery

What is a limitation of using only a power-rating table to predict energy use for a week?

AIt does not show how long or how often each device actually runs.

BIt shows energy use without needing time data.

CIt cannot list units for power ratings.

DIt proves all devices have the same efficiency.

Solution & Explanation:A power rating gives rate of energy transfer. Weekly energy use also requires actual operating time and patterns of use.
