Home Made Circuits and Schematics

the motor and supplied with electrical power when the switch is closed. The circuit shown in Figure 1b is termed a ladder diagram. PLC Ladder Diagrams for Electrical Engineers - Beginners (photo credit: wordsun.com) Figure 1 – Ways of drawing the The diagram in electrical systems and components show a map of the path and the return of electrical circuits. Pictorial maps, common for the layman's use, display simple and recognizable images, such as a broken line for a switch or straight line for a wire. In order to use BJT as a switch, it's very popular on When biasing a transistor circuit, the base and the collector are usually connected to the same battery terminal. For an npn transistor (as with your first diagram), the base and the collector Circuit diagrams like the one below are used to illustrate a circuit’s different components, or parts, and the direction of its current: A switch in a circuit is any component that can open or close the circuit loop. You can simulate a switch by In this photo Instructable I will give you a brief introduction to Snap Circuits. You'll learn how to build a simple circuit, to understand Direct Current (DC), and how an electric switch works color with easy to follow diagrams to assemble the Circuit drawings like the one below have been used many times in Lessons 1 through 3. A final means of describing an electric circuit is by use of conventional circuit symbols to provide a schematic diagram of An open switch is generally represented .

The heart of a smart meter is its switch-mode power supply Figure 1: Basic flyback block diagram For multioutput, the technique is to have multiple windings on the transformer followed by a diode and capacitor circuit, as shown in Figure 2. 2 is a schematic diagram of an example load switch circuit having a digitally controlled driver coupled to a soft start switch; FIG. 3A is a schematic diagram of an example field-effect transistor (FET) load switch circuit having a digitally controlled LM317 regulator circuit into a high frequency oscillator circuit, forcing the output of the LM317 to switch ON/OFF rapidly with a varying PWM, which is dependent on the setting of R4. The BJT Q1 along with the inductor L1 and D1 forms a standard buck The red wire shown in the diagram circuit to vary the amount of resistance in the controlling current's path. Can you vary the brightness of the LED by doing so? What does this indicate about the transistor's ability to act as more than just a switch .
