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-plaque has an emf of 0.15 V and internal resistance of 0.25 \(\Omega\) . The water surrounding the eel completes a circuit between the head and its tail. If the water surrounding it has a resistance of 500 \(\Omega\) , the current an eel can produce in water is about
