Difference Between Ammeter & Voltmeter

The major difference between the ammeter and the voltmeter is that the ammeter measures the flow of current, whereas the voltmeter measures the emf or voltage across any two points of the electrical circuit. The other differences between the ammeter and voltmeter are presented below in the comparison chart. Electricity is measured in two ways. i.e.,…

Difference Between CFL & LED Bulbs

The major difference between the CFL and LED is that in CFL the emission of light is because of the ionisation of mercury vapour. The mercury vapour when ionise produces ultraviolet rays. These rays when collides with phosphorous coating tube generates visible light. Whereas in the LED it is because of the PN junction diode. When…

Difference Between PN Junction & Zener Diode

The major difference between PN junction and the Zener diode is that the PN junction diode allows current to pass only in the forward direction, whereas the Zener diode allows the current to flow both in the forward and the reversed direction. The other differences between the PN-junction and Zener diode are shown in the…

Difference Between kW & kWh

The most significant difference between the kW and kWh is that the KW measure the power generate and utilise by the devices, whereas the kWh measure the energy consumed by the electrical equipment. The other differences between kW and kWh are explained below in the comparison chart. The word demand shows the kW, and the word…

Difference Between Avalanche & Zener Breakdown

One of the major difference between the Avalanche and the Zener breakdown is that the Avalanche breakdown occurs because of the collision of the electrons, whereas the Zener breakdown occurs because of the high electric field. The other differences between them are explained below in the comparison chart. The charge carrier of the PN-junction diode…

Difference Between Forward & Reverse Biasing

One of the major difference between the forward and the reverse biasing is that in forward biasing the positive terminal of the battery is connected to the p-type semiconductor material and the negative terminal is connected to the n-type semiconductor material. Whereas in reverse bias the n-type material is connected to the positive terminal of…

Difference Between Alternator & Generator

The major difference between the alternator and the generator is that in alternator the armature is stationary and the field system rotates whereas in the generator armature rotates and field is stationary. The armature of the alternator is mounted on the stationary element called stator and field winding on a rotating element. While the connection…

Difference Between Volts & Watts

One of the major difference between volts and watts is that the volt is the SI unit of potential difference and electromotive force, whereas the watt measures the SI unit of power. The other differences between them are explained below in the comparison chart. Both the volts and watts are related to each other. The…

Difference Between NPN & PNP Transistor

One of the major difference between the NPN and PNP transistor is that in the NPN transistor the current flow between collector to emitter when the positive supply is given to the base, whereas in PNP transistor the charge carrier flows from the emitter to collector when negative supply is given to the base. The…

Difference Between Diode & Transistor

One of the major difference between the diode and the transistor is that the diode converts the alternating current into direct current while the transistor transfers the input signals from the low resistance circuit to high resistance circuit. The other differences between them are explained below in the tabulated form. The diode is also known…
