Electric eel electricity

Physics Education, 2020
Abstract Motivated by the concept of evolution, we surveyed the values of electric current feasible for the electric eel by reconfiguring the series-parallel combination of its biological cells called electroplaques. In particular, using a simple algebraic method, we found out the best series-parallel combination with which the eel ...

The Electric Sense of Weakly Electric Fish

Annual Review of Physiology, 1984
Recent studies of electroreception have been particularly successful in three different areas: Electroreceptors are tuned to the dominant frequency of the animal's EOD, and their tuning follows natural and experimentally induced shifts in EOD frequency.

Batteries for Electric and Hybrid-Electric Vehicles

Annual Review of Chemical and Biomolecular Engineering, 2010
Batteries have powered vehicles for more than a century, but recent advances, especially in lithium-ion (Li-ion) batteries, are bringing a new generation of electric-powered vehicles to the market. Key barriers to progress include system cost and lifetime, and derive from the difficulty of making a high-energy, high-power, and reversible ...

Electric emissions from electrical appliances

Radiation Protection Dosimetry, 2007
Electric emissions from electric appliances are frequently considered negligible, and standards consider electric appliances to comply without testing. By investigating 122 household devices of 63 different categories, it could be shown that emitted electric field levels do not justify general disregard.

Electric Light and Electricity

Theory, Culture & Society, 2013
This paper argues that cultural analyses of electric light, including aspects of actor-network theory, may raise the spectre of complexity, but do not do it justice when they omit to provide analysis of the intertwined roles of culture and political economy in the formation of the provision and use of electric light.

Modeling the electric chain of an electric boat

2011 IEEE EUROCON - International Conference on Computer as a Tool, 2011
Electric boats can constitute a valid solution to face the nowadays energy paradigm. Among other advantages, the electric chains on-board of a boat can be efficient and environmental friendly. In this paper, the electric chain of an electric boat is modeled using as reference a low scale system.

Electrical Safety

2009
Since the purpose of clinical neurophysiology testing is to record the electrical activity of the nervous system, and often to electrically stimulate the peripheral or central nervous system (for evoked potentials, nerve conduction studies, etc.), these tests by their very nature demand an excellent electrical connection to the patient.
