What is Resistor, Symbol, Types, Resistor Color Coding


A resistor is an electronic component. The work of a resistor is to resist the flow of electricity. This flow of electricity is called current. In other words, the resistor stops the overflow of electricity. Every resistor has values that tell how resists current flow. This resistance value is called ohm. The resistance is used … Read more

What is Diode, Uses, Symbol, Types (Zener, LED, Avalanche, PIN, Schottky)


A diode is made up of two words that is di means two, and ‘ode’ means electrodes which means that a device or component has two electrodes. Diode have two electrodes anode and cathode. Most diodes are made with semiconductor materials such as silicon, germanium or selenium. Anode have a positive charge and cathode have … Read more

Logic Gates (OR, AND, NOT, NOR, NAND, XOR, XNOR) Truth Table

Logic gates

Logic Gates are defined as digital circuits that operates on one or more digital inputs and produces an one output signal. Logic gates are called digital circuits because the input and output signals are either lower voltage(0) or high voltage(1). These are also called logic circuits because they can be easily analysed by Boolean algebra. … Read more

What is Digital Multimeter (DMM), Working and How to Use?

Digital Multimeter

A Digital Multimeter (DMM), is a test instrument that is used to measure electrical values, for example, voltage, current, resistance, continuity, and many other measurements. Digital multimeters are widely used in the industries by electricians, electronic engineers, some hobbyists, etc. The price of the digital multimeter varies. Some can be purchased very cheaply and others … Read more

What is Transducer and Different types of Transducers?


A transducer is a device used to convert one form of energy into another. The process of converting one form of energy into another is called transduction. An electrical transducer is a device that is capable of converting physical quantities proportional to electrical quantities such as electrical current or voltage. The physical quantity that is … Read more

Ohm’s Law- Definition, Formula, Examples

Ohm’s law is a formula that states the relationship between Voltage ‘V’, Current ‘I’, and Resistance ‘R’ in an electric circuit. It is one of the important and most basic laws of electrical circuits. Before proceeding further in detail with Ohm’s Law, we ought to understand the three important terms that are Voltage, Current, and … Read more
