# Electric Current: Resistors Color Code

### Key Concepts

• 3 brand resistor
• 4 brand resistor
• 5 brand resistor

## Introduction:

Electrical appliances are connected to the same voltage, but different current flows in the circuit. Different resistors are placed in the circuits, which offer different resistances to the flow of electrons. In this section, we are going to observe these different resistors and calculate their resistance.

## Explanation:

### Resistor:

A resistor has a band on it, which can be used to calculate its resistance. It can be three, four, five or six bands. Based on the bands on the resistor, its resistance can be calculated. This resistance of that resistor is fixed.

Its SI unit is Ohm.

Following is the table with color code of resistors.

GD: Make this in the form of a table with each color’s name as the row’s color.

Following is the table with the tolerance of resistors.

GD: Make this in the form of a table with each color’s name as the row’s color.

Calculation (in four band resistor):

First band is the first digit of resistance.

Second band is the second digit of resistance.

Third band represents the multiplier of resistance.

Fourth band represents the percentage of accuracy between the indicated value and the actual value.

Question 1: Match the following

Question 2:  Calculate the resistance, minimum resistance and maximum resistance of this resistor.

Resistance= 6.4 GΩ ±0.5%

Minimum resistance = 6.368 GΩ

Maximum resistance = 6.432 GΩ

### Summary

• Resistor has 3, 4,5 or 6 color band.
• Color code:
1. First band is the first digit
2. Second band is the second digit
3. Third band is the multiplier
4. Fourth band is the tolerance.
• Standard color associates each color with a specific decimal digit (0-9)

#### Define Position Time Graph and its Types

Key Concepts • Slope of a graph • Position time graph • Slope of s-t graph = Velocity • Types of position time graphs Introduction An object in a uniform motion covers equal distances in equal intervals of time. This also indicates that it moves at a constant velocity. When its position at different instants […]

#### Magnetic Field Lines: Definition, Explanation and Q&A

Key Concepts Magnetic Field Magnetic Field Lines properties of magnetic field lines Uniform and non uniform magnetic lines Introduction Two magnets when placed close to each other attract and stick to each other. However, if we go on increasing the distance between them, the attraction between them reduces gradually to such an extent that they […]
