The concluding section ends by silver coated copper connections plated tin is then pressed on the bullion resistor.<\/span> While the possibility of another way, there are some carbon rod mill that has been formed, surrounding the connection is made such that the connection seems set.<\/span> So that in this way allows a mechanical look better and stronger, and can reduce the risk of electrical noise as a result of a bad connection.<\/span><\/p>\n

The last process is all the resistors are given a plastic coating or varnish that serves as electrical insulation and protection against moisture wet air.<\/span>

According to ohm’s law can be stated:<\/span>
\n v (t) = i (t).<\/span> R<\/span>
\n Where<\/span>
\n v (t) = voltage to change the time (t)<\/span>
\n i (t) = current with respect to the change of time (t)<\/span>
\n R = resistance value in (ohms)<\/span><\/p>\n

In the film resistors are made by depositing a resistive material uniformly high quality ceramic bars.<\/span> Reistor material can be either pure carbon (carbon membrane);<\/span> chromium nickel (metal membrane);<\/span> a mixture of metal and glass (metal layer);<\/span> or metal and oxide (metal oxide).<\/span> Selection of ceramic rod is very important because it can increase and decrease the value of resistor properties.<\/span><\/p>\n

For example, in order to avoid cracking, the thermal expansion must be equal to the thermal expansion of the film material.<\/span> The common material used is aluminum.<\/span> Then the resistance value can be determined by making a circular incision trace \/ threaded portion of the resistive film material.<\/span> By arranging a very close distance such that the resistance value can be enlarged up to 100 times more.<\/span><\/p>\n

The technique of making this screw has the advantage that the error factor \/ tolerances can be fixed up very tightly to \u00b1 1% or better.<\/span> In the resistor film types, relationship types of materials used and the thickness of the coating film determine the initial resistance value.<\/span> For example, the material of the metal film of chromium-nickel with a thickness of 150A (0015 m), will provide about 125 \u03a9 resistance value per unit area.<\/span><\/p>\n

Equations On film resistors – metal layer, the manufacturing process is as follows: First, a piece of metal, either chromium, tungsten, thallium, tantalum, or other types, ground into small particles in the micron size.<\/span> Furthermore, the metal has become the powder mixed with glass powder of similar size with an organic solvent.<\/span> Percentage mixture of powdered glass with metal powder will determine the sheet resistance of the material layer, or also called resistive ink.<\/span><\/p>\n

Then the resistance in the form of the sheet, coated on a ceramic rod, then heated at a temperature of about 1150 ^{\u00b0<\/sup> C for approximately 30 minutes.<\/span> In this process causes the glass powder melts and begins to flow, thereby attaching coating on the ceramic rods and produce resistor with resistance value is very stable.<\/span><\/p>\n}

The end was given the cover with tin-plated copper connection and the determination of the resistance value is made with slices of trace threaded patterns on layers using a diamond wheel.<\/span> Resistor which has been completed is then coated with electrically insulating plastic material and protection against environmental influences.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
