## What does 4R7 resistor mean?

4.7 ohms

Lower values use “R” as a decimal point. For example 4R7 = 4.7 ohms, 34R8 = 34.8 ohms.

**What resistor is orange orange red gold?**

The fourth band (or 5th for the 5-band and 6-band) indicates the tolerance values. Here, two colors are added (gold and silver). The 6th band for a 6-band type resistor is the temperature coefficient….Resistor Band Colors.

Color | Value |
---|---|

Red | 2 |

Orange | 3 |

Yellow | 4 |

Green | 5 |

### What is r in resistor value?

R = resistance of resistor in ohms ( ) V = voltage across resistor in volts (V)

**What resistor is green blue red gold?**

4 band resistor These resistors have two bands for the resistance value, one multiplier and one tolerance band. In the example shown here, the 4 bands are green, blue, red and gold.

## What does the J on a resistor mean?

+- 5%

Tolerance is indicated as. F = +- 1% G = +- 2% J = +- 5% K = +- 10%

**What is red red red gold in resistor colour coding?**

Third band represents the decimal multiplier after the first-two significant figures of resistor value. Fourth band represents the tolerance of resistor. According to colour code : red (2) orange (3) gold (5 %). Thus resistance value is 22×103±5% Ω.

### Is R same as ohm?

where I is the current through the conductor in units of amperes, V is the voltage measured across the conductor in units of volts, and R is the resistance of the conductor in units of ohms. More specifically, Ohm’s law states that the R in this relation is constant, independent of the current.

**What is M in resistor?**

Every 1,000,000 Ohms is known as a Megohm (Mega = one million), abbreviated to the capital letter “M”. As a couple of examples; a 4,700 Ohm resistor would be written as either 4.7K or 4K7, and 5,600,000 Ohms would be written as 5.6M or 5M6.

## How do you remember resistance color codes?

The resistor colour codes can be remembered with the help of mnemonic device “BB ROY of Great Britain had a Very Good Wife,” the capital letters represent the first letters of the colours and their positions the digit values.

**Do light bulbs follow Ohm’s law?**

Neither the incandescent bulb nor the LED will follow Ohm’s Law, neither produces a linear graph.
