Amwoga KhalwaleConduction, convection and radiation are the three major ways in which thermal energy can be transferred from one object/substance to another or from a system to its surroundings. Both conduction and convection requires matter to transfer heat. However, if there is a temperature difference between two systems heat will always find a way to transfer … Read more
What Is A Resistor? A resistor is a passive two-terminal electrical component with the primary function of limiting the flow of current in a circuit, a function that is key to the operation of most circuits. They are typically constructed of metal wire or carbon and engineered to maintain a stable resistance value over a … Read more
What Is Substitution Reaction? A substitution reaction is also referred to as a single displacement reaction, single substitution reaction or single replacement reaction. Substitution reaction can be described as a reaction in which the functional group of one chemical compound is substituted by another group or it is a reaction which involves the replacement of … Read more
The generation in computers is used to refer to the change in or state of technology a computer is or was being used. In the early 1950s the term generation was used to describe the various changing aspects of hardware technologies. Today, in the world of computers, the term generation describes both hardware and software, … Read more
What Is Single Precision? Single precision is a format proposed by IEEE for representation of floating-point number. It occupies 32 bits in a computer memory; it represents a wide dynamic range of numeric values by using a floating radix point. A floating-point variable can represent a wider range of numbers than a fixed-point variable of … Read more
Hazel Eyes Hazel eyes are sometimes mistaken for green or brown eyes. They are not as rare as green eyes, but are rarer than blue eyes. Only about 5 percent of the population worldwide has the hazel eye genetic mutation. After brown eyes, they have the most melanin. . The combination of having less melanin … Read more
What Is An Adder? An adder is a digital circuit that performs addition of numbers. In many computers and other kinds of processors adders are used in the arithmetic logic units or ALU. They are also used in other parts of the processor, where they are used to calculate addresses, table indices, increment and decrement … Read more
A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by excess current from an overload or short circuit. Its basic function is to interrupt current flow after a fault is detected. There are different types of circuit breakers made in varying sizes, from small devices that … Read more
What Is Lone Pair? When two elements of a pair are joined together with the surface contact between them, the joint is referred to as lower pair. Area of two elements comes together when relative motion occurs between the elements to form a lower pair e.g nut and screw, universal joint used to connect two … Read more
Volt and ampere are two measures of electrical current or flow of electrons. They define characteristics of an electricity supply. Voltage is a measure of the pressure that allows electrons to flow while ampere is a measure of the volume of electrons. These measurements of supply allow us to calculate the power a supply can … Read more
