Student Name:
Date:
Instructions:
Each of the following slides contains a construction site photo that depicts one or more electrical hazards. There is also an electrical theory math slide following the photo slides.
Examine each photo, and answer the questions in the notes section of each slide. Make sure to also move the red arrow (provided in the bottom left corner of each slide) to point toward the location of the hazard. Also, provide an answer in the notes section of the electrical theory math slide. Show your work for the calculation that you are asked to perform.
Save the completed presentation, and upload it to Blackboard.
Be sure to put your name at the top of this first slide!

Electrical Theory Math Quiz
Calculate the current (in amperes) flowing through the following two circuits given the following:
Voltage = 125
R1 = 15 Ohms
R2 = 20 Ohms
R3 = 5 Ohms
Be sure to show your work!
Hint: You will find guidance on how to complete this calculation in the unit lesson.
Circuit #1: Series
Circuit #2: Parallel
