* Idea # 2: Investigate electroplaques and suggest why an electric eel can kill its prey without injuring itself Case study brief Electroplaques are cells within animals like the electric eel. They are stacked in series and parallel and this arrangement can generate large voltages and currents that can be used to kill or stun prey. Candidates can find out about the chemical processes which lead to the generation of an emf in these biological cells, revise ideas on parallel and series, consolidate ideas about internal resistance and explain why the electric eel doesnt injure itself. that is the full topic. APA format. 3 pages single spaced. i will be attaching the rubric.
