Definition: The potentiometer which is used for measuring the phase and the magnitude of the unknown emf by comparing it with the known emf such type of potentiometer is known as the AC potentiometer. The working principle of the AC potentiometer is same as that of the DC potentiometer, i.e., the unknown voltage is determined by …
The most significant difference between the magnetic field and the magnetic flux is that the magnetic field is the region around the magnet where the moving charge experiences a force, whereas the magnetic flux shows the quantity or strength of magnetic lines produced by the magnet. The other differences between the magnetic field and magnetic …

Definition: The instrument designs for measuring the unknown voltage by comparing it with the known voltage, such type of instrument is known as the potentiometer. In other words, the potentiometer is the three terminal device used for measuring the potential differences by manually varying the resistances. The known voltage is drawn by the cell or any …
The most significant difference between the galvanometer and ammeter is that the galvanometer show both the direction and the magnitude of the current, whereas the ammeter only shows the magnitude of the current. The other differences between the galvanometer and the ammeter are shown below in the comparison chart. The galvanometer uses a moving coil …
Definition: The signal generator is an electronic device which induces the repeating and non-repeating analogue or digital signals.The signal generator is extensively used in troubleshooting, signal tracing, testing, adjustment of amplifier response and alignment of radio and T.V circuit. The signal generator has inbuilt modulation property. The amplitude and modulation property are very common in …
Definition: The instruments in which the measured quantity produces physical effects which deflect or displace the moving system of the instruments in known as the deflection type instrument. In other words, the instrument in which the deflection provides the basis for measuring the electrical quantity is known as the deflection type instrument. Such type of …
Definition: The LCD is defined as the diode that uses small cells and the ionised gases for the production of images. The LCD works on the modulating property of light. The light modulation is the technique of sending and receiving the signal through the light. The liquid crystal consumes a small amount of energy because …
Definition: The LED is a PN-junction diode which emits light when an electric current passes through it in the forward direction. In the LED, the recombination of charge carrier takes place. The electron from the N-side and the hole from the P-side are combined and gives the energy in the form of heat and light. …
One of the major difference between the LED and the LCD is that the LED uses the PN-Junction diode which emits light when the current passing through it, whereas LCD uses liquid crystal or plasma for visible light emission. The liquid crystals are filled between the glass electrode and when the power is applied across it, …
Definition: The digital storage oscilloscope is defined as the oscilloscope which stores and analysis the signal digitally, i.e. in the form of 1 or 0 preferably storing them as analogue signals. The digital oscilloscope takes an input signal, store them and then display it on the screen. The digital oscilloscope has advanced features of storage, …
