Logic gates  The gates operation is based on Boolean algebra, which involves variables that have only two possible values: true (1) and false (0).Logic gates are fundamental building blocks used in digital circuits. “Logic gates are digital circuits or electronic circuits that manipulate  voltages, so, in effect, they manipulate the binary ones and zeros  which are moving around inside your computer.” Logic gates , and the innovative ways in which they may be combined, are thus necessary for the proper functioning of a digital computer. Boolean expression “The relationship between input and output is called Boolean expression and is  represented in binary numbers.” Binary numbers have only two possibilities. Zero and one. When dealing with the circuits, zero corresponds with the circuit in the off state and one corresponds with the circuit in the on state.  So, if we are dealing with true or false statements zero is considered false and one is considered true. I...

1k/10k Resistor color code chart A resistor is a general electronic component used in electronic circuits. It protects the circuits from over-current and maintains the limit of signals. It is a passive component of the integrated circuits. The resistor value expresses in resistance, and the unit is the ohm. What is the resistor color code? To identify the value of the resistor, we can use two methods, calculating the ohm resistor value ( resistor calculator ) or by resistor color code (truth table). A resistor calculator or a resistor color code table is used to understand the value of the resistor. We use these methods for normal-size resistors. At the capacitor, the code number is printed on it. There is a significant digit number code written on SMD-type resistors and capacitors. But 5 watt or more wattage metal oxide film resistor contains written detail. Also, a high-voltage resistor, that is used in printers and copier machines, has written specifications on it. How resistor col...

Types of batteries and Used in components A battery is a device that contains chemical energy, stores it, and converts it into electrical energy. There are some batteries that are made with cells connected in series. It was Alessandro Volta who invented the battery in 1800. With these batteries, the voltage fluctuated and there was an insufficient current. Types of Battery Materials There are many types of batteries, that are categorized according to construction, size, and usage. But all the batteries are the source of DC voltage. The battery capacity depends upon its ampere value. 1- Nickel-cadmium 2 - Lithium ion 3- Zinc-carbon   4- Silver oxide 5- Lead-acid Nickel-Cadmium batteries Nickel-cadmium batteries or NiCad batteries have a long service life and could last for years. But the disadvantage is the toxic material. However, it has the advantage of being unable to overcharge. Lithium metal batteries We use some batteries cell in small devices. We use the single cell in s...
