Grouping of Cells Grouping of Cells :- It isn’t possible to make voltage sources and batteries for each specific voltage requirement. When a different voltage is necessary, two or more voltage sources(cells/batteries) are used in different combinations to produce the desired value of voltage and current. These cells can be connected in two basic types…
No of Images Formed by Two Plane Mirrors No of Images Formed by Two Plane Mirrors depends on the position of mirrors with respect to each others and also on the position of object between the mirrors. Let us discuses different positions of mirrors:- Case (I) – Image Formation by Parallel Plane Mirrors…
