two primary cells9 Distinguish between emf and terminal PD of a cell What are their units10 Derive net emf of two cells connected in series

LEVEL 2

11 What happens to the drift velocity (vd) of electrons and to the resistance R if length of a conductor is doubled (keeping potential difference unchanged)( Ans vd halved and R becomes four times )

12 A conductor of length L is connected to a DC source of emf If this conductor is replaced by another conductor of same material and same area of cross section but length is 3L How will the drift velocity change

(Ans vrsquod = vd3 )13 Draw a plot showing the variation of terminal voltage (V) vs the current (I) drawn from

the cell Using this plot how does one determine the internal resistance of the cell (Hint r = -ve slope of V-I graph )

14 In the arrangement of resistors shown what fraction of current I will pass through 5 resistor

(Ans 2 I3 )

15 In a meter bridge two unknown resistances R and S when connected in the two gaps give a null point at 40 cm away from one end What is the ratio of R and S
