$$\text { Figure } 3

Question

$$\text { Figure } 3 < 1$$
-If the voltage is  15 V  and resistance is color coded red-red-brown-silver in Figure  3-1 , what are the maximum and minimum possible current?

Quizplus · Accepted Answer

According to Ohm's Law, I = V/R. 
The resistance of red-red-brown-silver is 220 Ohms +/- 10%. 
Therefore, the minimum resistance is 198 Ohms (220 Ohms - 10%) and the maximum resistance is 242 Ohms (220 Ohms + 10%). 
Using the maximum resistance, I = V/R = 15V/242Ohms = 62.0 mA (rounded to one decimal place). 
Using the minimum resistance, I = V/R = 15V/198Ohms = 75.8 mA (rounded to one decimal place). 
Therefore, the correct answer is C.
