They are still used today because of their low resistive values and high-power ratings.

Wire wound resistors were the first type of resistors to ever be used. Like the name indicates, these resistors are wires of about the same length which are made from copper-nickel manganese alloy, nickel chromium alloy, or some other type of alloy. Wire wound resistors come in different sizes and aesthetics. Let’s go over the different types of resistors now. You can always tell the difference between each resistor based on their color code. This is not true because resistors are different based on their size and rating. Most people don’t realize this and just assume that all resistors are the same. There are several types of resistors to choose from in the marketplace. Ohm represents the unit of resistance used when talking about resistors. As the electric current flows through the circuit, the resistor creates resistance to limit the passage of the flow. Within an electronic circuit, the value of the current and voltage must be maintained and regulated. Most electronic devices and circuits have resistors in them.
