The most difficult electricity riddles A list of electricity related questions that are most often answered incorrectly Technology quiz What is the unit of the conductance?1S (siemens). Conductance (conductivity) is the reverse of the resistance. So it is a measure of the susceptibility of the element to the flow of the electric current. Siemens is the unit of electric conductance named after German inventor and industrialist Werner von Siemens, founder of the well known Siemens company.hard 42% 1Ω (ohm)1Ω (ohm)19%1S (siemens)1S (siemens)42%1H (henry)1H (henry)13%1T (tesla)1T (tesla)24%Created by: Paweł Kołodziejczyk.

Electric eels inhabit muddy waters of the Amazon and Orinoco basins floodplains and swamps. Fortunately, these are remote and uninhabited areas, as electric eels can easily kill a human. Although it doesn't eat such large animals (it has no teeth and can swallow only small mammals), a series of electric shocks is enough to stun and drown a horse.hard 50% in Australiain Australia18%in South Americain South America50%in Africain Africa8%in South-East Asiain South-East Asia21%Created by: Sumit Tamang.

Any lead-acid battery system when overcharged will produce hydrogen gas by electrolysis of water. If the rate of overcharge is small, the vents of each cell allow the dissipation of the gas. A severe overcharge may produce a flammable concentration of hydrogen.hard 52% acid leakacid leak23%polarization switchpolarization switch10%explosionexplosion52%sulfurizationsulfurization13%Created by: globalquiz.org.

Kirchhoff's current law is also called Kirchhoff's first law, Kirchhoff's point rule, or Kirchhoff's junction rule (or nodal rule). The principle of conservation of electric charge implies that: At any node (junction) in an electrical circuit, the sum of currents flowing into that node is equal to the sum of currents flowing out of that node or equivalently The algebraic sum of currents in a network of conductors meeting at a point is zero. average 61% Ampère's circuit lawsAmpère's circuit laws12%Kirchhoff's circuit lawsKirchhoff's circuit laws61%Faraday's circuit lawsFaraday's circuit laws10%Ohm's circuit lawsOhm's circuit laws14%Created by: Paweł Kołodziejczyk.
