  Hi guys! today we will be talking about Why Digital Era is consider as the Best era of the modern history ? Beginning: As we all know before 1980 things were done manually to tell something to someone who lives miles a part from you we need to write letters to them and it was a time taking process we don't even know that whether our letter has been received by that person or not. another thing was that for entertainment purpose people used to listen to radio for news updates or any other thing such as sports score, commentary etc.  for getting up to date information was not an easy process in that they have to rely upon newspapers for getting the info. Hence that era was a difficult era. Beginning Of the Digital Era: in the year 1980 digital electronics came into existence and the first thing that came out was a cellphone with buttons and speaker which was used for making calls. people were really impress that they were able to call someone who lives miles a part from t...

 Another important thing about this component is that people think that there are +ive and -ive terminals of the resistor but the real fact is that there are two cases for that Case 1: As it is a component which use for resistance and its simplest example can be given like a wall.                   if you ever recognize that what are the functions of wall, basically its a big block containing a flat and a smooth surface the functions of both is to provide the resistance or blockage in that case. Same goes for the resistors. Case 2: Another case is that for a resistor to have a positive or a negative terminal that it should be a part of a circuit let us get explanation from this example, consider wall having two surfaces one on the other side and one on the other side, now if a country is attached to that side of the wall lets say Pakistan then that side would be consider as a Pakistani side where as on the other side of the wall belongs ...

Hi ! there today we are going to share an interesting information about resistors. Resistors are basically small components that are used in various electronic device's such as mobiles, computers, Tv's, and many other accessories such as kitchen accessories which include microwave, blenders, toasters etc. Metal film resistors are usually made of Nichrome, but also other materials such as tantalum nitride is used . The resistive film is printed on a cylindrical or flat insulating substrate. Function of a Resistor: The main function of a resistor in any circuit is that it helps to resist a specified amount of current which is not required in a circuit it helps in saving the components from being short circuit.  A typical Resistor:   but there are many drawbacks of them, the can only resist a certain amount of current in the circuit. Resistors are also classified on the basis of their power weightage. 1 . Resistor having power (1/4 w): this is a resistor which is having a power o...
