## 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.
