Date______________

Concepts: Resistance, Voltage Available, Voltage Drop, Series Circuit Current

-----------------------

Directions: 1. Build the series circuit pictured at the left on the Project Board

Instructor Check [ ] 2. Have the instructor approve the build.

& conversation

3. Begin by making an un-powered resistance test of the loads

(bulb, resistor, diode, motor).

Bulb #1: _____Ω Bulb #2: _____ Ω

4. Power up the Electrical Project Board. Determine the OCV (open

circuit voltage or source voltage).

Open Circuit voltage: _____ V

5. Determine the voltage available to each of the loads (consumers).

Voltage Available to Bulb #1: _____ V

Voltage Available to Bulb #2: _____ V

Instructor Check [ ] 6. Determine the voltage drops at each of the loads, the switch, and

& conversation the ground wire. Record your results. Add up the voltage drops

to determine total VD for the circuit and record the total VD.

Voltage Drop of Bulb #1: _____ V

Voltage Drop of Bulb #2: _____ V

Voltage Drop of Ground Wire: _____ V

Voltage Drop of Switch: _____ V

Total Circuit Voltage Drop: _____ V

Instructor Check [ ] 7. Switch the leads & the meter to measure amperage (current).

& conversation Remove the fuse. Measure the current with the meter in series.

Circuit Current: _____ mA _____ A
