Most of the film resistors of the type of metal layer has a nominal value of a typical power dissipation of 250mW sebasar up to a nominal value of 2W. In the resistor wire windings are made by wrapping the resistance wire in an insulating material. Resistance of materials commonly used is chromium-nickel (nichrome), the compounds of nickel (Eureka), and ...

Resistor serves to inhibit current and dividing voltage, nominal resistance value and tolerance shown by the tape of a resistor color code on the resistor body. The first color and the second is the value of the unit, and tens, the third color indicates the number zero and the fourth color is tolerance. Example: A resistor has the color in ...

If the resistor, it only has a resistance value of the inductor she has a resistance value (R) and the value of inductance (L). Where the magnitude of the inductance value depends on the number of windings (N), the windings cross-sectional area (A) and the long axis of the windings (l). Mathematical relation can be written as follows: μo is ...

A. The series Series If we connect the two prisoners in a row as in Figure 1:32, then the circuit is called a series of series / series. Figure 2.11. Series with two resistors From the graph above shows that the magnitude of VR is the sum of the voltage drop on each resistor. If the series with three resistors ...
