Grouping of cells Series: Eeq = ∑E1 And req = ∑ri; . If S number of identical cells each of marking (E, r) are connected in series across an external resistor R. Eeq = SE And req = Sr ⇒ . Out of these S cells if x number of cells are reversely connected then Eeq = (S – 2x)E, . Parallel: If P number of Read more about GROUPING OF CELLS[…]
1st Law / Junction Rule: Across any junction algebraic sum of all currents is zero; this is a consequence of Conservation of charge principle. 2nd Law / Loop Rule: This is a consequence of conservation of energy principle. Across any loop i.e. closed path work done by all agents is equal to zero. This follows from Read more about Kirchhoff’s Laws[…]
Dipole: Electric Dipole and Dipole Moment: Two equal and opposite charges separated by a distance together constitute a dipole.Dipole moment defined as the simple product of magnitude of either charge and the distance of separation between the two charges. . Dipole moment always points from -q to +q. Its SI unit is coulomb metre (Cm). ELECTRIC FIELD DUE TO Read more about ELECTRIC DIPOLE, its MOMENT, INTENSITY[…]
Hello guys..!! Hope you all must be waiting eagerly for our next article. Here goes an explanation and derivation of escape velocity and its applications. Escape Velocity: It is the minimum velocity with which a body must be protected from the surface of the earth so that it escapes from the gravitational field of the Read more about Escape Velocity and Orbital Velocity of Satellite[…]
