error of the resistors wired in series.

(Give both quantitative and percent

error.)

(1) First,

you

must

find

the

total

(disregarding

the

tolerances).

Rt = r1 + r2 = 68.50 + 14.30 = 82.80 ohms.

(Rt = R = calculated value)

(2) Maximum quantitative system error.

A = (0.030 + 0.020) = 0.050 ohm.

(3) Maximum percent system error.

volts) across a load resistor (250 ohms 0.1), by the formula:

P = unknown power

V = measured voltage

R = load resistor

(1) First, find the unknown power and then find the maximum possible

quantitative error of the calculated power due to uncertainty of the

measurements.
