CalculationsNeed to calculate Percent Error based on the above data (for series and parallel?) %error = [(actual value - measured value)/measured value] * 100
Q1. Do your calculated values of R1 and R2 compare favorably with the stated values of the resistor? How do you account for the difference?
Q2. How do stated and measured values of R1 and R2 compare with one another?
Total Resistance
R=V/I
R= (3.1 V) / (0.0055 A)
R= 562 ?
Series Resistance
R= R1 + R2
R= 374 ? + 188 ?
R= 562 ?
Parallel Resistance
R= (R¬¬1*R¬2) / ( R1 + R¬2)
R= (362 ? * 184 ?)
(362 ? + 184 ?)
R= 122 ?
