Voltage Drop Lesson

CONGRATULATIONS!!!You have completed the voltage drop STAiR lesson .

GOOD JOB Question 1Using your DVOM place you leads on either side of the load. Circuit with signal load on a open circuit.

What is the power or voltage used over the light on the open circuit?NEXTINCORRECTNEXTINCORRECTNEXTCORRECTNEXT

12.00 volts

6.00 volts

0 volts

8 voltsINCORRECTNEXTINCORRECTNEXTINCORRECTNEXTCorrectNEXTThis circuit is closed with two load devices. When two equal load devices are used, half of the voltage or power is used over each load. So 12 volts would be split over the two lights. Or six volts used over each light. 6.00 volts, 6.00 volts.LegendBatteryGroundOpen switchClosed switchResistanceDVOM (Digital volt ohm meter)

NEXT

An open circuit where power is interrupted by an open switch, their would beno power used over the load device. Place the DVOM leads on either side of the load device and set your meter to direct voltage. The meter will read the total power used over the load device.Since the circuit is open no power is used

NEXTA closed circuit where power flows through a closed switch, their would betotal power used over the load device when there is only one load device (light bulb).Place the DVOM leads on either side of the load device and set your meter to direct voltage. The meter will read the total power used over the load device.

NEXTPlace leads from your DVOM on either side of the load devices. This circuit contains two equal loads. Since the circuit is open the power used over both loads is equal to 0v.

NEXTPlace leads from your DVOM on either side of the load devices. This circuit contains two equal loads. The circuit is closed so power is flowing through the loads, the loads are equal so power used over each load is equal. 6.0 volts used over each load.
