Q.

Eels are able to generate current with biological cells called electro plaques. The electroplaques in an eel are arranged in 100 rows, each row stretching horizontally along the body of the fish containing 5000 electroplaques. The arrangement is suggestively shown here. Each electroplaques has an emf of 0.15V and internal resistance of 0.25Ω . The water surrounding the eel completes a circuit between the head and its tail. If the water surrounding it has a resistance of 500Ω, the current an eel can produce in water is about

emf in each row = 0.15 × 5000 = 750V
resistance of each row = 0.25 × 5000 = 1250V
total resistance of 100 rows =1250100=12.5Ω
 current i=75012.5+500=750512.5=1.461.5A
