In a previous article, we discussed various types of fixed resistors, selection of resistor type for a given circuit, and identifying value, tolerance and power rating of fixed resistors. Let’s now talk about variable resistors. The resistance of variable resistors can be adjusted manually or digitally. The variable resistors offer a range of resistance instead…

In the previous article, we discussed composition and film type fixed value resistors. Continuing the discussion on fixed resistors, now let us talk about wirewound, foil and semiconductor type fixed resistors. Wirewound Resistors Wirewound resistors are made by winding a resistive wire around a non-conducting core. The resistive wire is usually made up of an…

In the previous article, we learned about various performance indicators associated with resistors. Now, let us learn about different types of resistors and how they score over various performance indicators. This evaluation will help in determining the suitability and relevance of different types of resistors for specific electronic applications. There are the following types of…
