Demodulation The terms detection or demodulation are often used when referring to the overall demodulation process. Essentially, the terms describe the same process, and the same circuits. Terms like diode detector, synchronous detector and product detector are widely used. But the term demodulation tends to be used more widely when referring to the process of Read more about Demodulation[…]
Electric Potential The electric potential at any point in an electric field is equal to the amount of work done per unit positive test charge or in bringing the unit positive test charge from infinite to that point against the electrostatic force without acceleration. Electric potential is a scalar quantity, it is denoted by V. Read more about Electric Potential[…]
Static Friction Friction is a force which comes into existence when two bodies in contact have relative motion or tending to have relative with respect to each other and oppose the motion. Types of Friction: There are three types of Friction: Kinetic Friction Static Friction Rolling friction What is a Static Friction? The frictional force Read more about Static Friction[…]
Kinetic Friction Friction is a force that tries to oppose motion between the two surfaces in placed contact. When we throw a ball on the floor it starting with some velocity. But once it is rolled ideally no force is acting in the direction of motion and according to Newton’s first law the ball should Read more about Kinetic Friction[…]
Mass and Weight What is Weight? Weight is the measure of the force of gravity acting on a body, The formula for weight it is given by: Weight(W) = Mass(M) x Acceleration due to gravity(g) As weight is a force its SI unit is also the same as that of force, SI unit of weight Read more about Mass and Weight[…]
Third Equation of Motion by Graphical Method Consider an object is moving with a uniform acceleration “a” along a straight line. The initial and final velocities of the object at time t = 0 and t = t are u and v respectively. During time t, let s be the total distance travelled by the Read more about Third Equation of Motion by Graphical Method[…]
Second Equation of Motion by Graphical Method Consider an object is moving with a uniform acceleration “a” along a straight line. The initial and final velocities of the object at time t = 0 and t = t are u and v respectively. During time t, let s be the total distance travelled by the Read more about Second Equation of Motion by Graphical Method[…]

Wavelength Wavelength is the distance from one crest to another, or from one trough to another, of a wave. Crest is the highest point of the wave whereas trough is the lowest. Since wavelength is distance/ length, it is measured in units of length such as metres, centimetres, millimetres, nanometres etc. Wavelength is represented with Read more about Wavelength[…]
Hooke’s Law On the application of stress on an elastic body, the strain experienced by the body is directly proportional to the stress applied. Hooke’s law is the basic law in elasticity, it states that the extension produced in a wire directly proportional to the load attached to it. Thus, according to Hooke’s law: Extension α Read more about Hooke’s Law[…]
