The next year, Davenport used an electric motor to propel a small car around a circular track, the first recorded instance of an electric railway.
In the instance of charging electric cars while inside a store, consumers could also make payments on the go using their vehicles.
The influence of particle size in a colloid viscosity is well known [48] due to effects, as for instance, of the electric double-layer repulsion.
The magnetoelectric effect can be very strong, for instance the change of electric polarization reaches 100 μC/m2 at a constant magnetic field of only 1.5 T in the case of 100 ÷ 10 nm structures which tightly fill the space, composing a metamaterial.
Electroluminescence is one of the few instances in which a direct conversion of electric energy into visible light takes place without the generation of heat, such as occurs in the incandescent lamp.
Current low oil prices may encourage oil burning and could postpone the market penetration of, for instance, electric cars.
An economic slowdown typically hurts manufacturers first -- because consumers and executives can more easily delay the purchase of new furniture than the payment of electric or medical bills, for instance -- but the contrast has been unusually severe recently.
For instance, an electric fan may reduce risk of malarial infection in infants and young children who stay at home, but not for older children and adults.
We demonstrate that, despite decoherence and disorder effects, minimal circuit instances allow us to investigate properties such as the dynamics of electric flux strings, signaling confinement in gauge invariant field theories.
The manager of the store in Manhattan, for instance, stocks electric fans well into November because New Yorkers live in small, hot apartments.
