Voltage divider rules states that Voltage divides in series circuit only. In parallel circuit voltage remains same. All of the loads are connected parallelly across voltage source so that loads have two common points with source positive and negative terminals. … [Read more...] about Voltage divider rule

## Kirchhoff’s law

Kirchhoff gave two laws for current and voltage. First law is called KCL and second law is called KVL. Kirchhoff’s current law (KCL): This is the first law of Kirchhoff’s about current. How current divide in a circuit this law explains. … [Read more...] about Kirchhoff’s law

## Norton’s theorem

American engineer Norton explained his theorem in 1926 after 43 years publishing Thevenin’s theorem. Norton’s theorem is similar to Thevenin’s theorem. Nortons theorem states that “a linear two terminal circuit can be replaced by an equivalent current source IN in parallel with a resistance RN where RN is the input or equivalent resistance at the terminals and IN is the short … [Read more...] about Norton’s theorem

## Thevenin’s theorem

Practically always occurs that a particular element like load is always variable when the other elements are fixed in a circuit. If we consider our household as example a household outlet terminal may be connected to different appliances constituting a variable load. Every time the variable is changed, the complete circuit has to be analyzed again. This is harassment for … [Read more...] about Thevenin’s theorem

## Inductor

An inductor is a passive two terminal element designed to store energy in its magnetic field. Inductor also called reactor or coil. It consists of conductor like wire wound into a coil. When current passing through the coil, energy is stored temporarily into the magnetic field. Applications of inductor in our daily life are transformers, power supplies, TVs, radios, radars etc. … [Read more...] about Inductor
