Measurement Answers

The student should measure around 5 to 6 volts for light bulb 1 and light bulb 2.

The student should measure around 10 to 13 volts across both light bulbs.

Calculation of Current

Student takes the total measured voltage. We will use 12 volts for our example.

\(R\:=\frac{\:V}{Ω}\:=\frac{\:12}{3.75\:+\:3.75}\:=\frac{\:12}{7.5}\:=\:1.6\)

Measured current should be similar to the example. It is often around 1.4 to 1.5 Ω.

The pictures that the students are submitting in the quiz are to reinforce the importance of lockout/tagout, verify, and safety glasses.
