Menghitung Nilai Resistor

Resistor is the basic electronic components used to limit the amount of current flowing in one circuit. As the name implies is a resistive resistor and generally made of carbon materials. From Ohms law is known, the resistance is inversely proportional to the amount of current flowing through it. Unit resistance of a resistor is called Ohm or represented by the symbol W (Omega).

A common type of resistor is shaped tube with two feet of copper on the left and right. In the body there is formed a circle bracelet color code to identify the user greater ease without measuring the amount of resistance with ohmmeter. Color code is the manufacturing standards issued by EIA (Electronic Industries Association). as shown in the table below.

Table Gelang Warna Resistor

Example:
The order of the color ring (4 rings resistor color (4 gelang warna)): red, Purple, blue, gold

• bracelet color 1: the first number
• bracelet color 2: the second number
• bracelet color 3: the multiplication factor
• bracelet color 4: tolerance

The order of the color rings (5 rings resistor color (5 gelang warna)): brown, red, black, orange, brown

• bracelet color 1: the first number
• bracelet color 2: the second number
• bracelet color 3: the third number
• bracelet color 4: the multiplication factor
• bracelet color 5: tolerance

The amount depends on the size watt resistor or the maximum power that can hold by resistors. Generally in the market available sizes 1 / 8, 1 / 4, 1, 2, 5, 10 and 20 watts. Resistor has a maximum power of 5, 10 and 20 watts is generally shaped white blocks and the value Direct printed dibadannya resistance, such as 1K 5W.

Basically, all materials have resistive properties but some materials such as copper, silver, gold and metal materials generally have very little resistance. These materials deliver the electrical current very well, so-called conductors. The opposite of a conductive material, materials such as rubber, glass, carbon has a greater resistance restrain the flow of electrons and are called insulators.

Resistor is the basic electronic components used to limit the amount of current flowing in one circuit. As the name implies is a resistive resistor and generally made of carbon materials. From Ohms law is known, the resistance is inversely proportional to the amount of current flowing through it. Unit resistance of a resistor is called Ohm or represented by the symbol W (Omega).

Resistor physical

Other specifications that need to be considered in choosing a design resitor the resistance is greater than big watts his. Because resistors working with electrified, there will be a power dissipation of heat for W = I2R watts. The greater the physical size of a resistor can demonstrate the greater ability of the resistor power dissipation.

Generally in the market available sizes 1 / 8, 1 / 4, 1, 2, 5, 10 and 20 watts. Resistor which has a power dissipation of 5, 10 and 20 watts generally cubic-shaped elongated white square, but there is also a cylindrical. But usually for this jumbo-sized resistor resistance value printed directly on the body, for example 100W5W.
