What is peak to peak voltage of a sine wave? Peak-to-peak (pk-pk) is the difference between the maximum positive and the maximum negative amplitudes of a waveform, as shown below. For an AC sine wave with no DC component, the peak-to-peak amplitude is equal to approximately 2.828 times the root-mean-square amplitude. What is a horizontal […]
What are the parameters that control the grinding process?
What are the parameters that control the grinding process? Selection of grinding process parameters. The grinding wheel speed, grinding wheel grade, depth of cut, grinding wheel material and feed rate are the important parameters that affect the surface finish, which in turn affects the productivity and cost of the component. What are the components of […]
What is the difference between a latch and a flip flop?
What is the difference between a latch and a flip flop? Both latches and flip-flops are circuit elements whose output depends not only on the current inputs, but also on previous inputs and outputs. The difference between a latch and a flip-flop is that a latch does not have a clock signal, whereas a flip-flop […]

What is the maximum displacement in a transverse wave?
What is the maximum displacement in a transverse wave? 2- A Crest is the maximum upwards displacement in a Transverse wave. 3- One complete wave cycle is referred to as a Wavelength . What is the maximum displacement of a wave? Amplitude, in physics, the maximum displacement or distance moved by a point on a […]
Is it possible to create a machine that runs forever?
Is it possible to create a machine that runs forever? Perpetual motion is the motion of bodies that continues forever in an unperturbed system. A perpetual motion machine is a hypothetical machine that can do work infinitely without an external energy source. This kind of machine is impossible, as it would violate the first or […]
What is the personal identification number on a debit card?
What is the personal identification number on a debit card? The Personal Identification Number or PIN is a unique four-digit code assigned to the card account number and known only to you. Your PIN is the access code to your account for all PIN point-of-sale purchases and ATM transactions. Memorize this number and do not […]
What is TV technology?
What is TV technology? The technology of television has evolved since its early days using a mechanical system invented by Paul Gottlieb Nipkow in 1884. While mechanically scanned systems were experimentally used, television as a mass medium was made practical by the development of electronic camera tubes and displays. How was television developed? By the […]
