Title: Lab 7-2 Quiz: Two Light Bulbs in Parallel Ohm's Law - 1 Hour
Course: Basic Electrical Theory and Wiring (Sandbox) > Section: Module 7: Ohm's Law

Q: What voltage drop did you measure across light bulb 1?

Q: What voltage drop did you measure across light bulb 2?

Q: What voltage drop did you measure across both light bulbs?

Q: What does this tell you about voltages in a parallel circuit?

Q: Calculate the total current of the circuit. Make sure to show all of your work and not just the final answer.

Q: What current did you measure going into the parallel lights?

Important!
Clamp around the black wire coming from the 2-way switch.

Q: What current did you measure going through Light 1?

Important!
Clamp around the white wire leaving Light 1. This should be the white wire that jumps between the light bulbs.

Q: What current did you measure going through Light 2?

Important!
Clamp around the black wire that jumps between the 2 light bulbs.

Q: What current did you measure leaving the circuit?

Important!
Clamp around the white wire that runs back to the ground/neutral bar.

Q: Explain in detail what is happening to the current.

Q: Did you perform lockout/tagout at the end of the lab?
- Yes
- No
A: Yes

Q: Did you verify with a multimeter that the voltage was at or near 0V after lockout/tagout?
- Yes
- No
A: Yes

Q: Did you wear your safety glasses the entire lab?
- Yes
- No
A: Yes
