Basic electronic components can be divided into passive and active components. Passive devices are resistors, capacitors, inductors and transformers. Active devices are diodes and transistors. Integrated circuits are
While direct current flows only in one direction, alternating current changes direction with a periodicity. Typical mains supply in this region has a frequency of 50 Hz or
Metals like iron, nickel, cobalt and some of their alloys can be attracted by magnets while those like copper, manganese and aluminium are not. A magnetic bar has
The ability of a conductor to allow free flow of electrons can be termed as conductance. It is the reciprocal of resistance and unit was called mho, which
Conductors are used in electronic circuits to carry electric currents between various parts of the circuits. Insulators are used when you do not want currents to get conducted
Kirchhoff’s circuit laws are two equalities that deal with the current and potential difference or voltage in electrical circuits, described in 1845 by German physicist Gustav Kirchhoff. Interestingly,
We discussed about conductors and insulators earlier. There is another group known as semiconductors like germanium and silicon which are bad conductors of electricity in their natural form.
