The magnetic field due to current in a circular loop and a solenoid
The magnetic flux lines emerge from the North pole to the South pole outside the coil, A circular loop carrying an electric current is like a magnet in the form of a disk has...

Magnetic effect of the electric current and Magnetic flux density due to current in two parallel wires
In 1819, a Danish physicist (Hans Oersted) brought a small compass near a wire carrying an electric current and parallel to it, He noticed that the compass needle deflected and when he turned the...
Ohm’s Law for the closed circuit, Relation between emf (VB) of an electric cell & voltage across its poles
The emf of an electric cell (battery – source) is the total work done inside and outside the cell to transfer electric charges in the electric circuit, If we denote the emf of the...
Resistances connection (series and parallel), Electric energy and Electric power
Electric resistances can be connected in the electric circuit using two methods which are series connection, parallel connection, Home appliances are connected in parallel, Thus every device can work individually on the potential difference...
