Exercise

Calculate the percent error of a 200- resistor with a silver band. The resistance was measured and found to have an actual value of 181 .

Is the resistance within the specified tolerance?

Type your answer in the box below:

Solution: Apply Equation (4.4)


A silver fourth band indicates a tolerance of ±10 %. Does –9.5% lie between +10 and –10 %? The answer is yes. Accordingly, the resistor is within the specified tolerance.
