ELECTRICAL MEASUREMENTS WITH DIRECT CURRENT
ANALYSIS
2. Assuming the voltage across the battery is known, use KVL to determine the voltage across the light bulb in Procedure 2, and enter in cell D55. Compare with the measured values by finding the percentage difference. Enter this value in cell D56 on the Worksheet.
3. Assuming the voltage across the battery is known and that the voltage across each bulb is the same, use KVL to determine the voltage across each light bulb in Procedure 3, and record the values in cells D61. Compare with the measured values by finding the percentage error in each case. Enter the errors in cells D63:D64.
4. In Procedure 4,
use KCL (applied at junction a) and the measured values of the current
passing through each light bulb to calculate the current passing through
the battery-leg of the circuit. Enter the current value in cell D68.
Compare with the measured value by finding the percentage error and entering
the result in cell D70.
