Question

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