Constant current generation of linear sweep voltage using op-amp?
When using the Op-amp we get constant current generation of the linear sweep voltage.
Difference between back EMF and induced EMF?
An induced electromotive force (emf) is an induced voltage. Voltage (emf) causes current flow, and this induced voltage will cause a current that is called the induced current.We might also add that the induced current will cause a magnetic field to expand about the current path, and this field will "sweep" the conductor. The sweeping of the conductor by that expanding magnetic field will set up an emf that will oppose the emf that was creating it.CommentTechnically, there is no such thing as an 'induced current'. It is voltage that is induced. Any current flows as a result of that induced voltage being applied to a load. But that current is certainly NOT induced!
What is voltage sweep generator?
A: Sometimes a spectrum of frequency must be analyzed a voltage to frequency converter can be used to sweep a range of frequency just by changing some DC level.
When a strong magnet is passed rapidly through a coil of wire what is true?
The magnetic field lines (the lines of force) around the magnet sweep the windings in the coil. This induces a voltage in the windings (through induction), and the voltage will try to drive current if it can. There is a bit more to this, but the essential elements are that the magentic lines of force cause voltage in the coil because there is relative motion between the field and the coil.
What is sweep speed error?
It is the ratio of the difference in slope at beggining and end of sweep to initial value of sweep.This error is due to deviation fron linearity.The important requirement of sweep is that it must vary linearly with time.

What is the difference between long turn and long radius in piping design?
Same thing consider the following Long turn ell ( Sweep) regular sweep and short sweep = 1/4 bend all are 90 degree fittings
What is a sweep test?
A sweep test is a method that determines the frequency response of a cable by its generation of RF voltage. This frequency should be varied at a rapid constant rate.
How do magnets generate electricity?
Magnets generate electricity by moving the magnet along a conductor, such as a wire. This is called induction. When magnetic lines of force sweep across a conductor, the magnetic field induces a voltage in the conductor. Voltage is "electrical pressure" and if a supporting circuit is set up connected to that conductor, current will flow.

How can display voltage current characteristics on a cathode ray tube?
-- Connect a diode and small resistor in series across a source of AC. -- Using the point where the diode and resistor meet as a common point, connect one scope probe (H or V) to the far end of the resistor, and the other scope probe to the far end of the diode. -- One dimension of the scope display now corresponds to the voltage across the diode. -- Since the voltage across the resistor corresponds to the current through it, the other dimension of the display corresponds to the diode current. -- I leave you to work out the scale factor for the current, and the various polarities.
