Thats why TT electronics resistors have kept circuits safe for more than 70 years and why TT electronics continues to o64256er the industrys most comprehensive range of circuit protection resistors In addition to o64256ering standard components TT e. p730 - 735. Essential Questions. How does the wiring in a circuit change its ability to supply power to devices?. How do we represent physical circuit elements in schematic drawings?. Objective(s. ): . pg. . 51. Objectives. Calculate the equivalent resistance for resistors connected in both series and parallel combinations.. Construct series and parallel circuits of lamps (resistors).. Observe and explain relative lamp brightness in series and parallel circuits. . Resistors in Series. PHET simulation. Resistors in Series. Total resistance for a circuit in series (. Rtotal. ). . Rtotal. = R1 + R2 + R3 + …. Ohm’s Law (V = I x R) . The R typically means total Resistance (. Brightness of lamps is depended upon the ______________ in a circuit. When all current travels in all of the devices, said to be in . Series. B/c current travels through all, current is same through out. Electric Power. How was power define before? . Time rate of doing work or using energy. Electric Power - Rate at converting electrical energy into other forms of energy. . P = W/t or P = E/t. Unit: watt, w = J/s. What is a Breadboard?. Sometimes called a proto-board. Reusable platform for temporarily built electronic circuits. Why Breadboard?. It takes less time (and money) to breadboard a circuit than to design and fabricate a printed circuit board (PCB. Eng.Mohammed. . Alsumady. Basics of Electronic Components. An electronic component is any device that handles electricity. Electronic components come in many different shapes and sizes, and perform different electrical functions depending upon the purpose for which they are used. Accordingly, electronic equipments make use of a variety of components.. Pre-Activity Discussion. © 2014 Project Lead The Way, Inc.. Digital Electronics. This Presentation Will…. 2. Introduce you to basic circuits and their symbols.. Introduce you to components and equipment that are fundamental to understanding circuits.. Vocabulary. Electric . charge. (q) – exists due to excess or deficient electrons on an object. Charge comes in two kinds: positive and negative. . The unit of charge is the coulomb.. Electric . current. Electromagnetic Force. The current in a circuit is driven by…. Generally, what . is needed for motion to take place?. Consider that electric current is the movement of electrons. what is the tension (pressure) on the current?. Resistance. Voltage. Current is a function of these two. What if we want to control the current or alter the voltage?. Change the Resistance!. How do we do this?. Which of the three parts of Ohm’s triangle do we have the most control over?. Activator. Essential Question:. How are series and parallel circuits similar and different in how they transfer energy. ?. Standard:. S8P5b. . Demonstrate the advantages and disadvantages of series and parallel circuits and how they transfer energy. resistors. A resistor, like batteries and lights, can also be present in an electrical circuit. A resistor limits the flow of electricity in the circuit. Like rocks in a pipe that slow the flow of water, a resistor will limit the flow of electricity. A variable resistor is made of a piece of metal that can change in length. As the length of the resistor changes, so does the resistance in the same direction. . Nature of science: . . Although Ohm and Barlow published their findings on the nature of electric current around the same time, little credence was given to Ohm. Barlow’s incorrect law was not initially criticized or investigated. This is a reflection of the nature of academia of the time with physics in Germany being largely non-mathematical and Barlow held in high respect in England. It indicates the need for the publication and peer review of research findings in recognized scientific journals..
