Unit 5 impedances Summary Resistors ar used in 2 main applications: as voltage dividers and to repair the pass of topical in a circuit. The measure of immovable oppositions sessnot be revisiond. in that respect are several types of fixed immunitys such(prenominal) as constitution snow, metal picture palace, and wire-wound. Carbon undergrounds change their guard with age or if overheated. Metal film oppositions never change their prize besides are more expensive than carbon resistivitys. The value of wire-wound resistos is their tall military group evaluates. Resistors often have bands of coloring material to indicate their resitance value and gross profit margin. Resistors are produced in standard values. The add of values between 0 and 100 ohms is determined by the tolerance. Variable resistors can change their value within the limit of their full value. A potentiometer is a variable resistor used as a voltage divider. Review questions shit three types of fixed resistors. What is the advantage of a metal film resistor over a carbon resistor? What is the advantage of a wire-wound resistor?

How should tubular wire-wound resistors be mounted and why? A .5-W, 2000-? resistor has a current flow of 0.01 A through it. Is this resistor operating within its power rating? A 1-W, 350- ? resistor is connected to 24V. is this resistor operating with its power rating? A resistor has color bands of orange, blue, yellow, and gold. What are the shelter and tolerance of this resistor? A 10,000- ? resistor has a tolerance of 5%. What are the minimum and maximum v alues of this resitor? Is 51,000 ? a stan! dard value for a 5% resistor? What is a potentiometer?If you neediness to get a full essay, order it on our website: OrderCustomPaper.com
