Question

1)N identical cells are connected in series .Calculate the equivalent r and emf.


2) n identical cells are connected in parallel. Calculate equivalent r internal resistance and equivalent emf

3) find equivalent emf and equivalent internal resistance of an arrangement when m identical cells are connected in series and n such rows in parallel

Answer 1

Answer:

Explanation:

1)net resistance(series combination)=r1+r2+r3+...+rn

emf=potential difference across the terminals

2)net internal resistance=e net/r +rnet
