Power Factor: What it is and Why it Matters?

Power factor

When it comes to electrical power, there’s more to it than just the amount of energy being consumed. One of the most important concepts in electrical engineering is the power factor, which refers to the ratio between the real power being used to perform work and the apparent power being supplied to the system. Real …

Amps Vs Volt? What’s the Difference

Amps Vs Volt

What is an amp (A)? An amp, or ampere, is the basic unit of electric current. It is defined as the flow of electrons through a conductor at the rate of one coulomb per second. In terms of SI units, an amp is equal to one coulomb per second, or amperes. The term “amp” can …

What is Earthing? Why it’s important?

earthing or grounding

Definition Geographically speaking earth is the planet habituated by mankind. What then can earthing mean? In layman’s language, is it connecting non-current carrying conductive parts of equipment or an installation to the earth using a conductor. It also refers to connecting the neutral conductor of an electrical system to the earth. Earthing is widely used …

Potential Difference and Measuring Potential Difference

potential difference explanation

Potential Difference If electrons have greater potential energy at one place than at another, then a potential difference is said to exist between the two places. Potential difference is the difference in potential energy per unit of charge, between two points.In the metric system, potential energy is measured in joules. The charge is measured in …

OHM’S LAW (Resistance and Voltage Drop)

ohm's law

OHM’S LAW There is a simple relationship between the current that flows through a conducting path and the potential difference between the ends of the path. As you increase the potential difference, the current increases, see the below circuit. The two values are proportional. That is, doubling the potential difference doubles the current. Tripling the …

What is Electric Resistance? Unit and Symbol

electric resistance

When any material flows through a pipe, it meets opposition. The opposition comes from friction between the material and the inner surface of the pipe. The friction resists the flow of the material, and it produces heat. The same is true of electricity flowing in a conductor. The moving electrons meet opposition, and the opposition …

Electrical Conductors

Electrical Conductors

In material science, there is the various classification of all matter in consideration of various important features. Some of the key modes of classification are in relation to electrical conductivity, heat conductivity, magnetism, level of permeability to water or fluids, compressional and tensional strength, ductility, and malleability among others. Today we shall look at one …
