Is a device that changes the voltage of an alternating current with little loss of energy?
The device you are referring to is called a transformer. Not only can a transformer increase voltage, it can decrease voltage as well. These are known as a step up transformer for increasing voltages and step down for decreasing voltages.
What causes 3-phase motors to heat up?
It is not only 3 phase motor, but every electrical device heats up. The reason is the current flowing through the windings causes the I^2*R heat loss. Apart from that, in case of an induction motor, the alternate cycle of magnetization and demagnetization of core material causes the hysterisis loss and eddy current loss. Last but not the least, there are friction and windage losses for a rotating electrical machine. All of these losses are dissipated as heat energy and hence the machine heats up.
Wires that do not have insulators there energy gets lost into the surroundings as?
Line loss, or heating of the wires. The insulators prevent the loss of energy.
What type of electrical bridge can be used for the measurement of dielectric loss of a capacitor?
Schering bridge
How can energy loss be minimised when trasnmitting electricity?

What energy transfers take place when you watch TV?
The main input energy is electrical energy from mains or power sockets; that energy is transferred to light energy for the pictures, and also there is sound energy (For audio), and all these energy are converted right back at heat energy as there is always a loss of energy in every device.
Why no power loss in pure inductance?
An inductor is a device which stores energy as a magnetic energy.... Ideal inductor have no resistance.....so there is no power loss.... power loss = (I*I)*R
Why the energy transfer from electrical energy to kinetic energy in a motor is not 100 percent?
There is energy loss in heating up the wires in the motor.
Materials that allow electrical charges to pass through them without electrical resistance and without loss of energy are called?
Superconductors
What does power loss in electrical transmission mean?
The term, 'power loss', describes the rate of energy losses caused by the load current in the transmission lines
What type of energy transformation occurs when a light bulb is turned on?
Electrical energy is transformed into heat and light. More specifically, electrical energy from the household wiring is turned into thermal energy (heat) by the filament which in turn becomes luminous energy (light). Some energy is lost due to resistance in the conductors.
What is loss load factor?
A load loss factor, LLF,not loss load factor,Êis a calculation used by electrical utility companies to measure energy loss.Ê Its the ratio of average load loss to peak load loss.
What type of energy transformation occurs when a light bulb is on?
Electrical energy is transferred into light energy, however if the light bulb is an older one, some energy will also be transferred into heat loss.

How much thermal energy is produced in an electric motor j of electrical energy are converted into 92j of mechanical energy?
Assume no vibration loss, the amount of energy input to electric motor subtract out the converted 92 J of mechanical energy is the thermal energy produced.
What happens to the electrical energy when power is transmitted through long distances?
Because wires are not perfect conductors, energy is released as heat. This is why electricity is transmitted at very high voltage and low current to reduce energy loss.
