PPT-DC Circuits I Physics 2415 Lecture 12

Michael Fowler UVa Todays Topics Mention of AC Semiconductors and superconductors Battery emf internal resistance Series and parallel resistances Kirchhoffs rules AC and DC Batteries. 1 Motivation Why is power dissipation so important Power dissipation considerations have become important not only from reliability point of view but they have assumed greater importance by the advent of portable battery driven devices like laptops c 1 Motivation We know that digital circuits are formed by two type of components 1 Combinational circuit and 2 Sequential Circuits Combinational circuit component s are used only for logic implementation and cant store the bits ie work as memory But N:2-3 / Series and Parallel Circuits. It’s a cool, clear night as you stroll by the harbor with your family. . The night is dark, but the waterfront is bright thanks to the thousands of twinkling white lights that outline the tall ships. . 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. ): . Shachar. Lovett (IAS). Joint with . Emanuele. Viola (Northeastern). Lower bounds. Classic lower bounds: . functions. . Bounded families of circuits cannot compute (or approximate) some explicit . function. 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. of Depth-Three and . Arithmetic Circuits with General Gates. Oded. . Goldreich. Weizmann Institute of Science. Based on Joint work with . Avi. . Wigderson. Original title. : . “On . the Size of Depth-Three Boolean Circuits for Computing . 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. 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. 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. Lecture 1. Michael Fowler. Basic Outline. The course has three main parts, each about a month: . Electrostatics.. Magnetism and Magnetic Induction.. Electromagnetic Waves.. We’ll cover some other waves, and optical phenomena, in the last few lectures. We’ll also cover DC and AC circuits in the course.. Michael Fowler, . UVa. Today’s Topics. Review self and mutual induction. LR. Circuits. LC. Circuits. Definition of Self-Inductance. For any shape conductor, when the current changes there is an induced emf . Michael Fowler, . UVa. Today’s Topics. Electric motors and galvanometers. Ratio of charge to mass for an electron. Hall Effect. Mass spectometry. Reviewing Essential Facts:. The force on an element of current in a wire in a magnetic field is:. Learn how to excel in AP Physics with this comprehensive guide.
