Eels are able to generate current with biological cells called electroplaques. 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 below. Each electroplaques has an emf of 0.15 V 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  500 ohm, the current an eel can produce in water is about
