Unfortunately, making the proper choices when sizing electrical conductors can get complicated. For one thing, the ampacity tables can be very confusing — especially if you don’t understand the “why” ...

A current carrying conductor creates a magnetic field around it, which can be comprehended by using magnetic lines of force or magnetic field lines. Magnetic field in a current carrying straight ...

Equipment: A compass, iron filings, a current carrying conductor and a 40 Amp power supply. What it does: The compass shows the direction of the field lines around the conductor. The iron filings line ...

To see a video on this topic by the author, click here. However, as the frequency increases; the current moves toward the outside of the conductor as indicated by the red and orange colors. This ...

The hindrance to the flow of electric charge is known as Resistance. The obstruction posed in the way of current carrying particles by fixed particles creates resistance in an electric circuit. Since ...

Fleming’s Left Hand Rule can be used to determine the direction of the force, current or magnetic field. This force forms the basis of the electric motor. A current carrying conductor creates its own ...

Facing scarcity of land and rising demand of power, the Maharashtra State Electricity Transmission Company Limited (MSETCL) - Mahatranso- has decided to install new power conductors to carry more ...

As we saw in Part 1, the correct sizing of conductors is more complicated than it appears. One of the reasons is the way temperature affects the resistance of a conductor. Higher temperatures mean ...
