PPT-Lecture - 3 Resistance equivalent circuits

Outline Resistors in series Resistors in parallel The voltage divider and the current divider circuits Voltage division and current division Measuring voltage and current The toY transformation. Standard 4NF1. Say What?. Let’s try it with numbers instead of letters.. ½ is equivalent to (2 x 1) / (2 x 2). So, ½ is equivalent to 2/4.. The Goose/Gander Rule. With equivalent fractions, there is always one important rule that must be followed.. for Power Gating Designs. Speaker: . Zong. -Wei . Syu. Dep. of EE, National Cheng Kung University. Date: . 2014/04/01. Introduction. Preliminaries . Problem Formulation. Partition Based Placement Algorithm. Bellwork. : Use the Ohm's law equation to determine the missing values in the following circuits.. Drawing Electrical. Circuit Diagrams. name variable unit symbol . source of . emf. ε volts V . I. Circuits. A flow of electrons is called a current.. Symbol - I. Unit is Amperes or Amps (A). I = q/t . Current is amount of charge per time.. B. What is a circuit?. A circuit is any . closed loop. Fractions the same as a ½. . Look at the shapes below, they all have ½ shaded but the half could be written in different ways.. 1/2 . 2/4. 3/6. 4/8. Look at those fractions again!. . 1. . 2. . AP Physics C. Internal Resistance. All components in a circuit off some type of resistance regardless of how large or small it is. Batteries especially have what is called an . internal resistance. , . 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. . For. example:. In this . lesson, . you . will learn how to identify equivalent fractions. . by . using a number line.. Fractions. 0. 1. Thinking fractions with different numerators and denominators are not equivalent. Suggested Problems. 15. The . current in a single-loop circuit with one resistance R is 5.0 A. When an additional resistance of 2.0 . Ω. is inserted in series with R, the current drops to 4.0 A. . What . Electric Current - . Flow of electrons through a material. Electrical Potential – . Similar to potential energy . Remember PE is . llifting. something higher against the force of gravity gives it greater potential to do work, increasing its potential energy.). What we’re now learning:. Series Circuit. A . series circuit . has a single path for the current. Series Circuit. There is only one path for the electrons to flow. This means the . current must flow through all loads. Exercise 1. Circle any equivalent ratios from the list below. . Ratio: 1:2 . Ratio: 5:10 . Ratio: 6:16 . Ratio: 12:32.  . Find the value of the following ratios, leaving your answer as a fraction, but re-write the fraction using the largest possible unit.. 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?. 李宏毅 . Hung-. yi. Lee. Textbook.
