A resistor is nothing magic. Take a long wire and measure the resistance, and you will realize that resistance is just a normal property of wires. 10 Simple Steps to Learn Electronics Electronics is easy when you know what to focus on and what to ignore. Learn what "the basics" really i...
An ohmic resistor is made ohmic because its function follows Ohm's law. Ohm's law essentially says that current is equal to voltage divided by resistance. Additionally, resistance is equal to voltage divided by current, and voltage is equal to current times resistance. Therefore, in a circuit,...
A resistor has a fixed resistance which does not change. A variable resistor is a single unit in the circuit where the resistance can be altered...Become a member and unlock all Study Answers Start today. Try it now Create an account Ask a question Our experts can an...
A Resistor is an electrical device that resists the flow ofelectrical current. It is a passive device used to control, or impede the flow of, electric current in an electric circuit by providing resistance, thereby developing a drop in voltage across the device. We need some way to control...
Chapter 1 - Resistor Fundamentals The resistor is a passive electrical component that creates resistance in the flow of electric current. In almost all electrical networks and electronic circuits they can be found. The resistance is measured in ohms (Ω). An ohm is the resistance that occurs whe...

A material that conducts electricity fairly well but not as well as a conductor is known as aresistor. The most common example of a resistor is a combination of carbon and clay, mixed in a specific ratio to produce a constant, predictable opposition to electric current. ...
What is a resistor?: This video spends quite a bit of time explaining how to read color codes; if you find the whole color system confusing, this is a good place to get your ideas clear.BooksFor younger readersEasy Electronics by Charles Platt. Maker Media, 2017. A simplified, comic-sty...
Thedefinition ofthe resistoris, it is a basic two-terminalelectrical and electronic componentused to restrict the current flow in a circuit. The resistance toward the flow of current will result in the voltage drop. These devices may provide a permanent, adjustable resistance value. The value of...
Their resistance value is either printed over the resistor or color-coded over them. The following are the types of fixed resistors. Carbon Composition Resistors : These resistors were used commonly in the past but are rarely used nowadays. Because of the use of a large negative temperature ...
