when 2 cells of different EMF and different internal resitsance are connected in parallel what is the current and effective internal resistance

rohit_student11

its e1/r1+e2/r2

ananth_patri

(e1/r1+e2/r2)r1r2/r1+r2....is net EMF....and net internal resistance is r1r2/r1+r2,,,,,,hope u got it..

plss rate me!!!!!!!!!!!!!!

HCV vol II , p.180

when 2 cells of different EMF and different internal resitsance are connected in parallel, then current

i = $\xi$ ₀ / r₀

where $\xi$ ₀ = ( $\xi$ ₁ r₂ + $\xi$ ₂ r₁ ) / ( r₁ + r₂ )

and r₀ = r₁ r₂ / ( r₁ + r₂ )
