Transcript: Electronic Circuit Jose Manuel Pinilla Cañaveral Santiago González Giraldo Sara Valbuena Torrenegra Group: 9 C Transformer Electrical Transformer Transformers are made up of different elements, the main ones being the core and the windings. The core of the transformers is made up of silicon steel sheets insulated from each other. They are made up of two main parts: the columns, which is the part where the windings are mounted, and the cylinder heads, which is the part where the union between the columns is made. The core is used to conduct the magnetic flux as it is a great conductor. Potentiometer Electronical Potentiometer A potentiometer is a passive electronic component. Potentiometers work by varying the position of a sliding contact across a uniform resistance. In a potentiometer, the entire input voltage is applied across the whole length of the resistor, and the output voltage is the voltage drop between the fixed and sliding contact as shown below. Frame Electronic Frame Is an element implemented by Netscape, which allows the screen to be divided into various areas independent of each other, and therefore with different contents, although they may be related. There are no limits to the content of each of these areas: they have the same properties as the normal full screen as we know it. Frames should not be confused with tables.
Transcript: OPERATIONAL AMPLIFIER Upon completion of this course, students should be able to: 1. Explain correctly the principles of electronic circuits by using block diagram or circuit schematic. (C4) 2. Conduct the construction of electronic circuits application during practical works based on the theory and principle operation of the circuits. (P4) 3. Deliver an oral presentation to display good communication skills. (A2) Filter Transformer: used to step the input AC voltage level up or down consists of two winding called the primary and secondary. the input to the transformer is applied to the primary and the output is taken from the secondary. operates based on the transformer ratio also known as the turns ratio of the component. the turns ratio of a transformer is equal to the voltage ratio of the component Example: A transformer with a turns ratio of 10 to 1, convert the 120V 60Hz sine wave input into a 12V sine wave. three types of transformer: i. step up transformer ii. step down transformer iii. isolation transformer OSCILLATOR LINEAR DC POWER SUPPLY RECTIFIER : Application of diode as: Constant Voltage Divider Circuit Rectifier R2 TIMER R1 A source of electric power (voltage and current) to operate electronic circuits. The most common source of energy for electronic circuits is obtained by converting the electrical energy available in the conventional alternating current (AC) electric power mains to an appropriate voltage or current. Examples: batteries, mechanically driven generators, photovoltaic (solar) cells, and fuel cells.

Explain correctly the principles of electronic circuits by using block diagram or circuit schematic. (C4) 2. Conduct the construction of electronic circuits application during practical works based on the theory and principle operation of the circuits. (P4) 3. Deliver an oral presentation to display good communication skills. (A2) 80V Forward biased: during "positive" half cycle of the AC sine wave, the diode is forward biased as the anode is positive with respect to the cathode resulting in current flowing through the diode. since the DC load is resistive (resistor, R), the current flowing in the load resistor is proportional to the voltage (Ohm´s Law), and the voltage across the load resistor will be the same as the supply voltage, Vs (minus Vf), that is the "DC" voltage across the load is sinusoidal for the first half cycle only so Vout = Vs. 20V HALF-WAVE RECTIFIER OPERATIONS EE301 ELECTRONIC CIRCUIT Voltage Regulator circuit Voltage Divider DC Power Supply Voltage Divider
Transcript: Electronic Siren Circuit The purpose of our project is to have the electrical energy travel through the circuit and create a siren noise through the speaker There are 13 different components in our circuit Switch: stops and starts circuits flow Speaker: plays sound of siren Capacitors: stores electric charge Resistors: Controls/ slows down electric current of circuit Transistors: semiconducter that has 3 prongs 1) amplifies 2) detects 3) or a switch We interpreted our circuit from a schematic It was difficult because even though it was correctly assembled, it did not function properly It took many different tries and we assembled it in 3 different ways before it finally worked. It would have been easier if directions were written correctly We experienced lots of frustration because it did not work properly and we had to redo it We have learned that making circuits takes lots of patience and focus to stay concentrated on assembling it properly After doing this project, all of have realized that we would never ever want to be associated with making circuits as a career

Transcript: There are many everyday products that we don't even think about. Topic The definition of miniaturization in terms of electronics is the decrease in size of electronic applications from nano-circuits to appliance chargers. This is mostly associated with nanotechnology Physical Science Timelines in Science pg.699 Writing About Science. Kevon Jamieson Electronic Circuit Miniaturization Photos There are multiple places where the spellchecker says that my spelling or use of words are incorrect. Disregard this because I have checked and all of it is correct. Products Which Use Nanotechnology Most nanotechnology today evolves electronics of some kind, which makes you think it would have to be a very recent work. But actually we have found forms of nanotechnological work dating all the way back to the 4th Century. The first actual technological form for of nanotechnology was the integrated circuit developed and created in 1958 by Jack Kilby.
