The total resistance of a body when subjected to a direct current shock is higher than the total impedance in case of alternating current
and at rms value of touch voltages lower than 150 V, as under such conditions the effect of capacitive reactance of the skin is significant.
"We are ultimately hoping to develop a device that, instead of delivering a painful, high-voltage shock when it detects a life-threatening arrhythmia, applies a more gentle alternating current
for the right amount of time to stop the dangerous rhythm.
Perhaps the best example of this is when he bought the patents rights for Nikola Tesla's alternating current
induction motor and his polyphase system of alternating current
According to Magnetek, power conditioners are designed to invert the direct current generated by fuel cells into "precise, reliable" alternating current
required to power most electrical equipment and enable the fuel cells to operate in both grid-tied or stand-alone modes.
At the time, George Westinghouse was selling residents of Manhattan alternating current
electricity as a cheaper alternative to Edison's direct current power.
For customers wondering whether alternating current
is right for their application, Mitsubishi Forklift Trucks has launched an easy-to-follow booklet--The Forklift Buyer's Guide to AC power?
While Thomas Edison was thrilling engineers with the development of the DC (direct current) motor, Tesla had already devised the far superior AC (alternating current
) model, which quickly became the industry standard."
An integral inverter changes the DC current to alternating current
for transmission into the facility's electrical distribution systems.
The alternating current
creates an expanding and collapsing magnetic field in a longitudinal direction across the coil windings.
The drive consists of an alternating current
AC induction electric motor and a frequency converter.
"Within the fair's alternating current
of order and transgression," Walden writes, "establishing the meaning of one almost necessarily required the presence of the other." (p.
To propel the train forward, an alternating current
of electricity flows through coils in the guide-way walls.
