4. The minimum resistance value for a blue, gray, red, silver resistor is ________.
(a) 612 Ω (b) 6,120 Ω (c) 6,800 Ω (d) 6,460 Ω
Answer
Answer : (b)
Explanation
Explanation :
Because of 10% tolerance (last color silver), this resistance may vary 10% of 6800 Ω.
Minimum resistance value = 6800 – 680 = 6120 Ω,
Maximum resistance value = 6800 + 680 = 7480 Ω.
Because of 5% tolerance (last color gold), this resistance may vary 5% of 1,20,000 Ω.
Minimum resistance value = 1,20,000 – 6,000 = 1,14,000 Ω,
Maximum resistance value = 1,20,000 + 6,000 = 1,26,000 Ω.
