The resistor is a passive two terminal electrical components, that are used in most of the circuits. The resistors act as the lower voltage levels within the circuit and it is also used for reducing the current. The high power resistors can drive may watts of electrical power like heat.

Wire Wound Power Resistor

A wirewound resistor is an electrical passive device that limits or restricts current flow in a circuit. Wirewound resistors are constructed using a conductive wire. The conductive wire is then wound around a non-conductive core. The conductive wire can be made of varying alloys and thickness to control the resistance value. Wirewound resistors are typically used in high power and industrial applications such as circuit breakers and fuses. Ohmite's 20 Series axial terminal resistors are both durable and economical.

Outline of a Resistor

As the name implies, the resistance of the variable resistor is changeable. It is easy to vary or change the resistance of a variable resistor to a desired value. Variable resistors are mostly used when the user do not know what exact resistance value does he want. The process of limiting or restricting the electric current to a certain level is called resistance. The device, which is used to restrict the flow of electric current to certain level, is called resistor. The device, which not only restricts the flow of electric current but also control increase and decrease the flow of electric current is called variable resistor. When we vary the resistance of a variable resistor to a higher resistance value, the electric current flowing through the variable resistor will decrease.

An ohm is an ohm, right? Not so fast — there are many different types of resistors. To insure that your circuit works and stays working, use the right type of resistor. In this article, you'll learn about the common types of resistors and their special characteristics. Every conductor exhibits some resistance to the flow of electrical charge except for superconductors.


As resistors are used in wide applications there values like power rating,R value, tolerance etc vary. Resistors of resistance value ranging from.1ohms to many.


Resistor & Types of Resistors | Fixed, Variable, Linear & Non-Linear

A wirewound resistor is an electrical passive device that limits or restricts current flow in a circuit. Wirewound resistors are constructed using a conductive wire. The conductive wire is then wound around a non-conductive core.

Resistors can be seen in almost all electronic circuits. There are many types of resistors and they can be divided into two groups namely fixed resistor and adjustable resistor variable resistor. The main function of the resistor is to resist the flow of electric current and regulate the flow of electrons. This is done by the material from which they are composed. They are mainly categorized on the basis of their applications, temperature coefficient, tolerance, size, power, reliability, voltage, etc.

Resistors: Types And Applications

There is a broad range of resistors. In order to know the position of ROHM's resistors, we have attempted to classify not only based on the general materials used, but also in terms of the shape, integration level, and functions.

Бринкерхофф застонал, сожалея, что попросил ее проверить отчет шифровалки. Он опустил глаза и посмотрел на ее протянутую руку. - Речь идет о засекреченной информации, хранящейся в личном помещении директора. Ты только представь себе, что будет, если об этом станет известно. - Директор в Южной Америке.

 - Скажи первое, что придет в голову. - Ассоциативный ряд? - по-прежнему недоумевал Дэвид. - Стандартная для АНБ процедура. Мне нужно знать, с кем я имею .

Тот, конечно, был мастером своего дела, но наемник остается наемником. Можно ли ему доверять. А не заберет ли он ключ .

Сьюзан едва ли не физически ощутила повисшее молчание. Оно показалось ей нескончаемо долгим. Наконец Стратмор заговорил.
