In an elecrical socket.
You could find an electric hand dryer at Home Depot or Lowes. I would recommend Excel. They have fantastic hand dryers that are very energy efficient.
the main source would be electric
Well, it would be solar to electric. Right? Because if the way to operate a gate has a solar panel, but the gate is electric, it would be solar to electric.
Electric Energy is the energy of the Universe. All energy is electric energy. Gravitational Energy is electric in the sense that matter is held together by electric energy. Briefly, Electric energy is E= - q1q2 zc/r where q is the electric charge, z is the free space resistance and c is the speed of light.
Not likely - any machine wastes some energy; that would reduce the useful output energy.
Someone can find electric storage heaters on any IKEA local store. One can also find electric storage heaters online at stores like Energy Saving Trust, Barry Gray and HW Electric UK.
Of course not! There is no direct relationship between electric current and electric energy. They aren't even measured in the same units. Also in most cases small electric currents provide less electric energy that very large electric currents. If all electric currents provided the same electric energy then the electric current from a flashlight battery that lights the bulb when you turn the switch on could provide the same electric energy as the electric current in a lightning bolt when it strikes... therefore every time you turned on a flashlight the electric energy would destroy the flashlight and electrocute you! As this doesn't happen, the only answer that your question can have is no!
Crating the Circuit alone would be electric energy and when the speaker is operating it would turn into sound energy.
Mechanical energy
Electric motors take electric energy and turn it into kinetic energy Generators take mechanical energy and turn it into electric energy
Electric energy to kitenic energy
An electric bulb, like an incandescent or LED bulb, can turn electric energy into heat and light energy. An electric motor can transform electric energy into motion energy.
