Explanation An inductor having the property of opposing to the sudden changes in the current, so that as the current changes are limited, the voltage across the inductor also limited from the relation voltage across an inductor v = L ( d i / d t ) . Sketch the given circuit as follows, Refer figure 1, the switch S 1 is closed the R-L circuit connects with a source emf ( ε ) . The inductor keeps maintaining the same current flow because of its property of opposing to the sudden changes in the current. The voltage across the inductor depends upon the rate of change of current d i / d t , Therefore the voltage across an inductor v b c is limited. The circuit must satisfy the Kirchhoff’s voltage rule for the loop, so that when source emf is adding to the loop other potentials must be change abruptly, so that v a c changes abruptly. Apply kirchaff’s voltage law for the loop ε = v a b + v b c The voltage drop across resistor R is v a b = i R , the voltage drop across inductor is v b c

Electromagnets

The word "electromagnet" is composed of two words, ‘electro’ and ‘magnet’. It is a type of magnet in which an electric current helps in the generation of a magnetic field. Electromagnets usually consist of two major parts, wire and a coil around which th…
