The image shows an unbalanced Wheatstone bridge. Find direction of conventional current between B and D.

The potential drop present across AD is lesser than the one across AB. Therefore, the potential of D is seen to be higher than the one of B. Thus, the flow is generally from D to B.

What is Wheatstone Bridge?

Wheatstone bridge, otherwise called resistance bridge, helps in the calculation of unknown resistance means of balancing two legs of the bridge circuit. Here, one of the legs contains the component of unknown resistance.

Construction of Wheatstone bridge

Wheatstone bridge circuit basically comprises of four arms. Wherein, two arms contain of known resistances while the other two arms consist of an unknown resistance and a variable resistance. In the construction of Wheatstone bridge, the circuit consists of a galvanometer as well as an electromotive force source. Herein, the emf source is connected between two points a and b.

On the other hand, the galvanometer is connected between points c and d. The current which is seen to flow via the galvanometer depends on the potential difference across it.

An astronomical telescope consists of two converging lenses. One of them of large aperture and large focal length is called objective lens and the other one, of smaller focal length and smaller aperture is called the eyepiece. It is used to see distant objects which are not seen clearly with naked eyes. The image formed by the objective lens acts as an object for the eyepiece and the final image produced by the eyepiece is magnified.
