CBSE Class 12-science Answered
Please help me with the following questions:-
1.state the condition in which the terminal voltage across a secondary cell is equal is equal to emf?
2.Assuming that electrons are free inside the solid, sketch graphically the distribution n(v) of electron with velocity v.
3.A potential difference v is applied across a conductor of length L and diameter D.How are the electric field E and the resistance R of the conductor effected when in turn:
(1)v is halved, (2)L is doubled, (2) Dis doubled? justify your answers in each case.

Please post one query at a time.
The terminal voltage across a secondary cell is equal to its e.m.f. when no current is drawn from it i.e., it is in an open circuit.
