Title: Lab 7-5 Quiz: DC LED Ohm's Law - 1 Hour
Course: Basic Electrical Theory and Wiring (Sandbox) > Section: Module 7: Ohm's Law

Q: Calculate the resistor size needed for the circuit. Show your work. I don't want just an answer.

Q: What resistor size did you actually use?

Q: What voltage drop did you measure across the resistor?

Q: What voltage drop did you measure across the LED?

Q: What current did you measure through the system?

Important!
Clamp around the brown wire. Zero the Extech until it reads 0. Then, press the push button to turn on the LED.

Q: Did Ohm's Law work for this lab? Please explain.
