How can we calculate tolerance value of resistors?

The tolerance band is silver, so we multiply our resistance by 0.1. This means that our resistor's value can be as high as 16.5 Ω or as low as 13.5 Ω. For the third resistor, we'll perform the calculation in an alternative way. Take the nominal value and multiply it by 1 + your tolerance, which is (1+0.1).
A.

What are the colors of resistors?

Components and wires are coded with colors to identify their value and function. The colors brown, red, green, blue, and violet are used as tolerance codes on 5-band resistors only. All 5-band resistors use a colored tolerance band.
B.

What is a resistor color code?

An electronic color code is used to indicate the values or ratings of electronic components, usually for resistors, but also for capacitors, inductors, diodes and others. A separate code, the 25-pair color code, is used to identify wires in some telecommunications cables.
C.

How do you read a resistor color code?

Steps
  1. Position the resistor with the gold or silver color band to the right..
  2. Read the color sequence that must be decoded to determine resistance.
  3. Determine the coded number for the resistive value.
  4. Determine the tolerance of the resistor.
  5. Determine the decoded number for the resistive value.
  • How do you read a capacitor?

    Method 2 Reading Compact Capacitor Codes
    1. Write down the first two digits of the capacitance.
    2. Use the third digit as a zero multiplier.
    3. Work out the capacitance units from context.
    4. Read codes that contain letters instead.
    5. Read the tolerance code on ceramic capacitors.
    6. Read letter-number-letter tolerance values.
  • Why are some resistors blue?

    The beige-colored body of a resistor is often an indication that its tolerance is 5%, while a blue-colored body often indicates a tolerance of 1% or 2%. The blue-bodied resistors and the dark brown resistor contain metal-oxide film elements, while the beige-bodied resistors and the green resistor contain carbon film.
  • What is the total equivalent resistance of the circuit?

    More resistance means less current is flowing through the circuit. Equivalent resistance is a different way of indicating 'total' resistance, which we calculate differently for series and parallel circuits. In a series circuit, the different components are connected in a single, continuous loop.
