Title: Lab 7-4 Quiz: DC Relay Coil 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 acorss the relay?

Q: What current did you measure through the relay?

Q: Calculate the resistance of the relay coil using the measurements that you just took. Show your work. I don't want just an answer.

Q: Measure the resistance of the relay coil.

Important!
Both wires must be removed and the screws tightened on the relay before taking your resistance measurement.

Q: How well do you think that Ohm's Law worked between your calculated and measured values? Please explain.

Q: Did you use the correct wire colors?

- Blue for 0V or Common
- Brown for 24V
- Yes
- No
A: Yes

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

Q: Did you verify that your voltage was off after your performed lockout/tagout?
- Yes
- No
A: Yes

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