Week 2 Lab Assignment: Basic Electricity

Recommended Materials
1. VOM Meter
2. Lab Sheet
3. Pencil
4. 24” x 24” Board
5. Electrical Wires
6. Three Light Bulbs
7. Switch

Scope

This lab will help the student to learn how to read volt, resistance, and amperage both mathematically and physically.

Procedures

1. Have instructor give you the supplies needed for this lab.
2. Your instructor will assign you equipment to work on.
3. On the test board, install three lights in series.
4. With the switch in the open position, measure of each light bulb and the resistance of the circuit. Record each reading.
5. Use ohm’s law to determine the Amperage. ( I=E/R)
6. Use a clamp-on amp-meter and measure the current flow.

Research Questions

1. Add the resistance of each light bulb. Does it equal the total resistance in the circuit?
2. What were the recorded amps?
3. Were the amps the same as the ohm’s law answer?
