Difference between Earthing and Grounding | Earthing vs Grounding

The main difference between earthing and grounding is that – Under Earthing, the circuit is physically connected to the ground to flow circulating current or fault current of the circuit to the protection of the system, Under Grounding, the circuit is physically connected to the ground to discharge the electrical energy to earth for protecting … Read more

What is Floating Neutral? Effects and How to Test and Fix it?

floating neutral

Floating neutral is a condition, in which the neutral wire of any circuit is disconnected from the ground. In AC system, the neutral wire is permanently grounded to the earth. However, floating neutral may occur in a power system due to loose connection, braking of neutral flat, wrong circuit connection, or due to short circuit. … Read more

Difference between volts and amps | Volts vs amps

Volts and amps (ampere) are the two different measures of Electricity. In a close circuit, the electric potential difference between two points is called Voltage and the flow of electrons through the close circuit is called electric current. The volts is the measure of voltage between two points and amps is the measure of electric … Read more

What is AC or Alternating Current?

AC or Alternating current is an electric current that continuously changes its magnitude with time and periodically reverses its direction. In Direct Current or DC, there is no change in direction, and the magnitude of the current is also the same. AC current is most commonly used for home and industrial purposes. Most of the … Read more

What is mAh in mobile battery?

mAh stands for milli Ampere hour which defines the total capacity of current a mobile battery can deliver in an hour time. To express the total storage capacity, the mAh rating is used in a mobile battery. A higher mAh rating means a higher storage capacity of the battery. For example, a battery rating of … Read more

Types of Cable Lugs

Cable lugs are used for termination or connection of cables to the Terminal Box (TB). There are so many types of cable lugs are available based on the cable size. They are mainly copper and aluminum type. Based on the application of the cables, following types of cable lugs are used for cable termination /connection … Read more

What is DC or Direct Current?

DC or Direct Current is electrical current which flows always in one direction. As we know, when electron flows from one place to another place, it is called electric current. Under Direct current, electron flows in one direction. Electron flows from the negative voltage terminal to positive voltage terminal and due to this DC flows … Read more
