What does 5w resistor mean?

It means that resistor of X ohms has capacity to dissipate 5 watts of power as heat without being destroyed. In other words they are also called as power resistors, they are used as loads for experiments or appliances.

What are standard resistor sizes?

The size of an axial resistor is relative to its power rating. A common ½W resistor measures about 9.2mm across, while a smaller ¼W resistor is about 6.3mm long. A half-watt (½W) resistor (above) sized up to a quarter-watt (¼W).

What is resistor number?

The Three and Four Digit Systems

In these systems, the first two or three digits indicate the numerical resistance value of the resistor and the last digit gives a multiplier. The number of the last digit indicates the power of ten by which to multiply the given resistor value.

What is the smallest resistor value?

YAGEO Group has recently developed the world’s smallest metal current sensing resistor – PA0100 (01005 size 0.4mm x 0.2mm).

How do you read a resistor band?

What happens if I use a higher watt resistor?

Wattage refers to the maximum that a resistor can dissipate. So subbing a higher wattage for lower is perfectly fine without any changes.

How do you calculate the value of a resistor?

Calculating. To calculate the resistance value, you need to group the values of the significant digits bands — i.e., the values of the first two or three bands from the left, depending on the total number of bands. Then you need to multiply that value by the multiplier to get the resistance value of the resistor.

How do you read a 5 band resistor?

Calculating resistance for a 5-band resistor
‘a’ represents the 1st significant digit, which is the first band color of resistor. ‘b’ represents the 2nd significant digit, which is the second band color of resistor. ‘c’ represents the 3rd significant digit, which is the third band color of resistor.

What are the 4 types of resistors?

Types of Resistors

• Fixed Value Resistors. These are the predominant type of resistor configuration, and as the name suggests, they have a fixed resistance value.
• Variable Resistors.
• Resistor Networks.
• Carbon Film Resistors.
• Metal Film Resistors.
• Wirewound Resistors.
• Metal Oxide Resistors.
• Metal Strip Resistors.

How are resistors rated?

Resistors are rated by the value of their resistance and the electrical power given in watts, (W) that they can safely dissipate based mainly upon their size.

How do you read resistor codes?

What resistor do I need for 5v LED?

Basics: Picking Resistors for LEDs

How do I know what wattage resistor to buy?

Generally speaking the larger their physical size the higher its wattage rating. However, it is always better to select a particular size resistor that is capable of dissipating two or more times the calculated power.
The Resistor Power Triangle.

How do I know what wattage resistor I need?

Assuming the LED has a maximum safe operating Amperage of I=0.02A , you can see that the Watt rating of the resistor should be at least P=V*I=3.3*0.02 = 0.066W . It’s better to take at least double the value (so 0.125W or more) just for the sake of safety.

What is resistor color code?

The colour code used to denote the tolerance rating of a resistor is given as: Brown = 1%, Red = 2%, Gold = 5%, Silver = 10 % If resistor has no fourth tolerance band then the default tolerance would be at 20%.

How do you read a 5 band resistor color code?

5 band color code resistor
The 1st color band indicates the 1st significant value or 1st digit of the resistors value. The 2nd color band indicates the 2nd significant value or 2nd digit of the resistor value. The 3rd color band indicates the 3rd significant value or 3rd digit of the resistors value.

What is the color code for a 5 ohm resistor?

The color code of the 1.01 ohm resistor for is brown – black – brown – silver – [Tolerance]. 1.02 ohm resistor color code for 5 band resistor is brown – black – red – silver – [Tolerance]. 1.04 ohm 5 band resistor color code is brown – black – yellow – silver – [Tolerance].

What are 5 examples of resistors?

Examples of Resistors

• Street Lighting. The street lights get automatically switched on in the evening and switched off in the sunlight.
• Laptop and Mobile Chargers.
• Temperature Control.
• Fan Speed Controller.
• Measuring Electrical Current.
• Temperature Sensor.
• In-Circuit Functioning.
• Dividing Voltage.

How do I choose a resistor for an LED?

Resistor = (Battery Voltage – LED voltage) / desired LED current. So assuming a 12-volt power source and a white LED with the desired current of 10 mA; The formula becomes Resistor = (12-3.4)/. 010 which is 860 ohms. Since this is not a standard value I would use an 820-ohm resistor.
