# Ohm's Law Problems

Table 1. Resistor values for stated value and measured value for R1 and R2 in Ohms.

R1

(Ω) R2

(Ω)

Stated Value 360 180

Measured Value 362 184

Table 2. Measured Currents and Voltages for series and parallel configuration with calculated resistances.

Series 5.5 5.5 5.5 3.1 2.06 1.034 562 374 188

Parallel 24.7 8.49 6.7 3.08 3.08 3.08 122 362 184

Calculations

Need to calculate Percent Error based on the above data (for series and parallel?)

%error = [(actual value - measured value)/measured value] * 100

QUESTIONS:

1. Do your calculated values of R1 and R2 compare favorably with the stated values of the resistor? How do you account for the difference?

2. How do stated and measured values of R1 and R2 compare with one another?
