A Complete Guide to Power Resistors

Posted by Nabin Shaw on October 17th, 2018

Power Resistors are basic components of electrical circuits. Scientists theorized the concept of resistance after they were conducting tests to determine the results of passing electricity through all kinds of materials. Subsequently, they have discovered electricity.

Some of these discoveries lead to the conclusion that copper, aluminum, and gold are great conductors but possess low resistance. Mica, air, and ceramics, on the other, were considered resistors because of their ability to limit greatly the flow of electrical current. Power resistors Canada did not come about this period though.

Even if the people in the industry are aware of its fundamental capabilities, they did not use them. It was only in 1961 that Otis Boykin first introduced a reliable resistor. He created a low-cost resistor that allow only a precise amount of electricity to pass through.

According to Renfrew Electric, this breakthrough that resistors were less affected by extreme temperatures and shock lead to their commercial manufacture. When the US military, IBM and many other consumer electronics manufacturer used the capacitors, it made its way to everything.

Uses of Power Resistors

Resistors have become omnipresent in today’s electronics. They are passive devices because the let the current passed through them but never produce power. Power resistors Canada are used to completing a circuit. In LEDs, they need a resistor to regulate the current flow. In the transistor, they control the amount of voltage that is reaching this active device. It can be used to conclude a transmission line and prevent reflections. In GPIO of a microcontroller, resistors are either a pull-up or a pull-down to create stability in the system.

The alternating resistor and capacitor in a series create the timing source, which is important in light flashers or in siren circuits that use electricity. A daisy chain of resistors that are connected in a series serves are a voltage divider. This is important to operate in a condition where there is a lesser voltage than the voltage supplied by the input.

Companies that are operating in the power resistor market are putting their focus in developing power resistors Canada that can dissipate a huge amount of power and at the same time making them portable. As to their technology, it now comes as wired resistors or power resistors with metal in their housing

Power Resistors at Renfrew Electric

Renfrew Electric has been manufacturing and selling power resistors in Canada since 1931. In the course of the existence in the industry, they have developed a wide customer base for their high-quality power resistors for a wide range of applications, heavy-duty relays, and loading banks for many loading requirements.

They are working with leading original equipment manufacturers (OEMs) and providing them with a range of integrated services. Their products include power wire-wound resistors, axial lead resistors, radial lead resistors, resistor hardware, heavy-duty mechanical relays, general-purpose relays, and load banks.

With their status as the leading manufacturer of power resistors and load banks, you can rely on their sophistication and commitment to help their clients from design to production. They have specific products for every requirement and will assist you until the project is finally delivered.
