THIS USER ASKED 👇

A resistor has four colored stripes in the following order: orange, orange, brown and silver. What is the resistance of the resistor and its tolerance

THIS IS THE BEST ANSWER 👇

Resistance = 330 Ω

Tolerance = 33 Ω

Explanation:

see attached resistor color code table

The first strip is orange, which means the longest left digit is 3.

The second strip is orange, which means the next 3 digits.

The third strip is brown. Since brown is 1, it means to put one zero to the right of the first two digits.

The resistance is:

orange-orange-brown = 330 Ω

The concession is:

The fourth color band indicates the tolerance of the resistor. The tolerance is the percentage of error in the resistance of the resistor.

10% money

A 330 Ω resistor has a silver tolerance band.

Concession = value of resistor x value of concession band

= 330 Ω x 10% = 33 Ω

Quoted resistance means 330 Ω +/- 33 Ω the resistor means the actual value range from as much as 363 Ω to as little as 297 Ω.
