pole position seats

="tblcel">The deflection in the galvanometer is reversed when the same pole of the magnet is moved in the opposite direction. The galvanometer pointer comes back to the zero position indicating that the deflection in the galvanometer lasts as long as there is relative motion bet..

The V E E supply is used to forward bias emitter base junction. As a result significant current flows, once the potential barrier is exceeded. The majority charge carriers diffuse from emitter into base and this results in emitter current I E as indicated in the above diagram. Once these reach the ..

The following sign convention is used for measuring various distances in the ray diagrams of spherical mirrors: Object is always placed to the left of mirror All distances are measured from the pole of the mirror. Distances measured in the direction of the incident ray are posit..

The transmission lines used in telephony are of two kinds: open- wire and cable. The open-wire lines are gradually being superseded by cable construction, either overhead or underground, for two principal reasons. In the first place, many more circuits can be accommodated-there is a standard cable ..

When the atoms forming bonds are different, the electron attracting powers of the two atoms in a bond may differ. Then, the shared pair will be displaced towards the atom having more electronegativity. For example, in a moleclule of HCl, the electronegativities of Cl and H are 3.0 and 2.1 respecti..

Summary - The science of magnetism is old. It has been known since ancient times that magnetic materials tend to point in the north-south direction: like magnetic poles repel and unlike ones attract; and cutting a bar magnet in two leads to two smaller magnets. Magnetic poles ca..

Three nuclei are towards the micropylar end, and form the egg apparatus with a central egg cell surrounded by 2 synergids . Three nuclei are at the chalazal end and form the antipodals . One nucleus from each pole moves to the central position of the embryo sac and are ca..

To concentrate solar radiations in solar heating devices. For this the food or substance that has to be heated is placed at the focus of a large concave reflector. After reflection, sun light converges on the substance and heats it. The following table gives the position, ..

. - The distances measured in the direction of incidence of light are taken as positive and vice-versa. - The heights measured upwards and perpendicular to the principal axis of the mirror are taken as positive and vice-versa. In case of both the spherical mirrors, convex and co..
