EE213 Electrical Circuits Laboratory Term Project Two Speed Automatic Transmission System 1. Introduction Transmission system is an assembly of gears‚ shafts and electrical gadgets in an automobile. This system forms a bridge between the engine and wheels to transmit mechanical power required for movement. The complete set up reduces the high rotational speed of engine to lower wheel speed‚ since internal combustion engines in automobiles operate between 600 and 7000 revolutions per minute (rpm)

SEMICONDUCTORS ELTE 1403 Forward biased diode: cathode anode Varactor is a silicon diode optimized for its variable capacitance when reversedbiased. Used for tuning frequencydependent equipment. Zener Diode is designed to operate in the breakdown region; used for voltage regulation. Varactor Zener N + P electron flow depletion layer An ideal diode acts like a closed switch when forward biased and an open switch when reverse biased. 1st approximation calculations assume

ABSTRACT Flood is one of the disastrous phenomena that caused a lot of deaths to some other uninformed area in the province. The researchers from Negros Occidental High School proposed a study with the objective to construct and develop a flood detection device‚ present a practical device‚ and introduce the device to a certain residents in the province that needs to be aware of flood. After the device was constructed‚ the researchers tested the device in a cup of water. During the testing of device

ELECTRONIC DICE . TO CONSTRUCT AN ELECTRONIC DICE USING LEDS . BACKGROUND: LED’s History The first known report of a light-emitting solid-state diode was made in 1907 by the British experimenter H. J. Round. However‚ no practical use was made of the discovery for several decades. Independently‚ Oleg Vladimirovich Losev published "Luminous carborundum [[silicon carbide]] detector and

load line. 1.2 AC OPERATION The experimental objectives are to: i) Compare the theoretical and practical amplifier voltage gain. ii) Determine the effect of the load on the amplifier voltage gain. . iii) Observe the effect of unbypassed emitter resistors. 2. INTRODUCTION: In this lab‚ the common-emitter configuration will be investigated. This common-emitter amplifier typically uses a self biasing scheme and has a relatively linear output. The common-emitter amplifier is characterized by

"Tee" configuration but the network can also be redrawn to form a Star or Υ type network as shown below. T-connected and Equivalent Star Network As we have already seen‚ we can redraw the T resistor network to produce an equivalent Star or Υ type network. But we can also convert a Pi or π type resistor network into an equivalent Delta or Δ type network as shown below. Pi-connected and Equivalent Delta Network. Having now defined exactly what is a Star and Delta connected network it is possible
