Voltage, Current and Resistance

The minimum resistance value for a blue, gray, red, silver resistor is

612

6,120

6,800

6,460

Answer: Option

Explanation:

Because of 10% tolerance(last color silver), this resistance may vary 10% of 6800.

Minimum resistance value = 6800 - 680 = 6120

Maximum resistance value = 6800 + 680 = 7480

Option b is correct as we have to consider the tolerance.

Of silver that is +/-10%.
