During a defensive discharge, an electric eel (Electrophorus electricus) generates a potential difference of 640 V across its electric organs.
A charge of 2.5 × 10-3 C flows through the surrounding water.
Calculate the energy transferred to the water.
Use the equation:
energy transferred=charge flow×potential difference \text{energy transferred} = \text{charge flow} \times \text{potential difference} energy transferred=charge flow×potential difference32 exam-style questions on Edexcel GCSE Physics 10.1 Circuits, charge and current, covering 10.1.1 Structure of the atom, 10.1.2 Circuit diagrams and symbols, 10.1.3 Series and parallel circuits, 10.1.4 Potential difference and voltmeters, 10.1.5 Energy transferred, charge and potential difference, and 10.1.6 Current, ammeters and charge flow.
