Two resistances `r_1` and `r_2`, when connected separately to the same potential difference, it was seen that the current flowing thought `r_1` was six times the current flowing through `r_2`. Determine the ratio of `r_1` and `r_2`.

Two cells each of emf e but internal resistance r_1 and r_2 are connected in series through an external resistance R. IF the potential difference across the first cell is szero while current flow, the relation of R in terms of r_1 and r_2

Two cells each emf e but of internal resistance r_1 and r_2 are connected in series through and external resistance R. IF the potential difference across the first cell is zero while current flows the value of R in terms of r_1 and r_2 is

Two resistances R and 2R are connected in parallel to an electric current Thermal energy developed in R and 2R are in the ratio :

IF three resistances are connected in parallel and the relation between then is R_1 gt R_2 gt R_3 , then the relation between the currents flowing through them is

If three resistances connected in series,are related as R_1 gt R_2 gt R_3 then what is the relation between the currents flowing through them?

A shunt of resistance r_1 is connected in parallel with a galvanometer of resistance G. A steady source of internal resistance r sends current through the galvanometer.Now, removing the shunt r_1 another resistances r_2 is connected in series with the galvanometer. (i) IF the galvanometer current in either case be the same , show that rG=r_1r_2, (ii) if r=0 and r_1=r_2=G/n , then show that the ratio of galvanometer currents in the two cases is (n+1)/n .
