![]() ![]() ![]() those worse than 1%, usually use a color code to indicate their value. Normally, general purpose components, i.e. For precision resistors, typically 1% tolerance or better, the nominal value is usually printed directly on the component. That is, there will always be some variance of the true value of the component when compared to its nameplate or nominal value. Like all components, resistors cannot be manufactured to perfection. The measurement of resistance in unpowered circuits may be performed with a digital multimeter. Its fundamental attribute is the restriction of electrical current flow: The greater the resistance, the greater the restriction of current. Resistors: The resistor is perhaps the most fundamental of all electrical devices. You can realize by figure, each green color line is series each other. The small leg is cathode and must be connected to the ground. LEDs have two legs, one of them is anode and the other one is cathode. ![]() LED is one of the most important component in electronics gives illumination or light. In this figure, simple LED example is given. The lab assistant teach you how to use the breadboard in lab. Each color lines are in series each other. A simple breadboard is shown in the figure. If you aren’t sure how a circuit will react under a given set of parameters, it’s best to build a prototype and test it out. Prototyping is the process of testing out an idea by creating a preliminary model from which other forms are developed or copied, and it is one of the most common uses for breadboards. These are great units for making temporary circuits and prototyping, and they require absolutely no soldering. Lab 1 : Introduction to Lab, Using materials Objective The objective of this exercise is to become familiar with the operation and usage of basic circuit materials, namely resistors, breadboard and Transistor-Transistor Logic ( TTL or chip).Įquipment (1) Adjustable DC Power Supply (1) Digital Multimeter (1) Resistors (1) Breadboardīreadboard: An electronics breadboard is actually referring to a solder less breadboard.
