1 Electrical & Computer Engineering
* 07/16/96 INEL 4075 Electrical Circuits Dr. Sandra Cruz-Pol Professor Electrical & Computer Engineering UPRM *

2 Basic Concepts Current Voltage Power Flujo de cargas
* 07/16/96 Basic Concepts Current Voltage Power Flujo de cargas Energía necesaria para que fluya Razón de tiempo a la que se consume o provee energía *

3 * 07/16/96 Example The battery of a flashlight develops 3V, and the current through the bulb is 200mA. What power is absorbed by the bulb? Find the energy absorbed by the bulb in a 5-minunte period. Answers: p= 0.6W, w= 180J *

4 * 07/16/96 Electrical Circuits We will take a look at several electricity components & concepts: Resistors Series & Parallel Connections Independent (e.g. Batteries) and Dependent Sources Capacitors, Inductors LED Nodes Chips (IC) It most have a closed loop *

5 Meet the Concepts: Resistor
* 07/16/96 Meet the Concepts: Resistor Black 1 Brown 2 Red 3 Orange 4 Yellow 5 Green 6 Blue 7 Purple 8 Gray 9 White Resistors- reduce or resist the flow of electrons *

6 * 07/16/96 v= Ri p= + v - i *

7 * 07/16/96 Series Connection Ley de Ohm V= I R *

8 Parallel Connection I = V / R Elements connect on both legs. *
07/16/96 Parallel Connection Elements connect on both legs. I = V / R *

9 Fuentes independientes
* 07/16/96 Fuentes independientes Es un generador de corriente o voltaje cuyo valor no depende de los componentes u otras variables en el circuito. + - v2 = 3 (V) *

10 * 07/16/96 Fuentes Dependientes Modelan comportamiento que depende de otro voltaje o corriente. Se usan para modelar transistores y amplificadores. + - v = 5i *

11 Metros Voltímetro – se conecta en paralelo
* 07/16/96 Metros Voltímetro – se conecta en paralelo Amperímetro- se conecta en serie *

12 * 07/16/96 Otros elementos Transducers - Convierten cantidades físicas en cantidades eléctricas Interruptores (switches) – conectan o abren el circuito *

13 * 07/16/96 What is a Node? How many nodes are in this circuit? *

14 * 07/16/96 LED Light emitting diodes (LED) like regular light bulbs but that are actually semiconductors that shine when an electrical current passes through them in a specific direction. Low Power consumption!  + *

15 What is a circuit Board? * 07/16/96 Nodes? *

16 * 07/16/96 Electronic Doorbell Switch Speaker *

17 * 07/16/96 Electro-magnet ***Warning!! It can get HOT. *

18 Where to find this material?
