ELECTRICAL MEASUREMENTS WITH DIRECT CURRENT
PROCEDURE
Open up the DC Workbook and fill in the header information. For each circuit below, draw a diagram in the space provided. Include your measurements in the spaces indicated on the Worksheet.
ELECTROMOTIVE FORCE & POTENTIAL DIFFERENCE
2. Create
a circuit made up of a battery, knife-switch and light bulb in series as
shown in Fig. 16-7. With the switch open, measure and record
the voltage across each component of the circuit, and record in cells D19:D21;
then close the switch and repeat the measurements and place the
values in cells D24:D26.
4. Create a circuit composed of a dry cell, a switch, and two light bulbs in parallel as shown in Fig. 16-9. With the switch closed, measure the current in each leg of this circuit, and record in cells D35:D37.
5. Obtain
a print out of the Worksheet and use it to develop your lab report.
