Note:
• *Nominal value is the Theoretical value for R.
• R'is the measured resistance value.
• Vis the theoretical voltage across each resistor.
V' is the measured voltage value across each resistor.
• I is the theoretical current passing through each resistor. Calculated using the theoretical
V and R values.
• I is the measured current passing through each resistor. Calculated using measured V
and R values.
• % error (R, v, 1) shows the deviation between the theoretical values and actual
measurements for the corresponding R, V, and I.
