Question

Deduce an expression for effective emf when two primary cells of emf e1 and e2 & internal resistance

r1,and r2, are connected in parallel.

A cell of emf (E) and internal resistance (r) is connected across a variable external resistance (R) Plot graphs

to show variation of (i) terminal p.d. of the cell V with R (ii) I with R (iii) I with​
