In energy terms, that means that of the original energy, a certain percentage - usually less than 100% - gets converted into the desired end form. The remainder gets converted into some waste energy; quite often, much of this waste energy is in the form of heat, which is - to a great extent - unusable.The details, how this happens, will vary from case to case. For example, friction may convert part of the energy into heat. Or an electrical current may pass through a resistor, where the current is converted to heat.
Usually, much of the wasted energy takes the form of heat energy. However, part of the energy can also be in other forms, for example sound.
Power = Energy/time 100W=Energy/360 Seconds Energy = 100/360 Energy ≈ 0.27 Joules
The Sun has an enormous amount of heat energy, but it seems logical that it has a much greater reserve of energy that has not been converted to heat yet - its nuclear fuel, in form of hydrogen.
A photocell converts light energy (radiant electromagnetic energy to be precise) into electrical energy. A thermocouple can convert heat into electrical energy. The radiant em conversion yields much more energy than a heat conversion.
Well, pressure energy can be converted into electrisity,in industries they use electricity to pressure for compress a object so if we have so much pressure we can create electricity.preessure will apply force on a body we know that force is also one form of energy so energy can be created.if you tell me in industries how they convert electricity into pressure we can definitely convert pressure to energy,bye.
I assume you mean magnetic energy. There is not much to convert there. A magnet doesn't store large amounts of energy. And especially, it is not an energy source - whatever energy you get out of it, you have to put in first.
none
The older generation of bulb(one in witch heating metal coil was used) convert electrical energy into both heat and light energy and consume more energy as some energy is lost as a heat energy. The newer generation of electrical bulb (C.F.L.) convert almost all electrical energy into light energy and consume much less electrical energy.
No There is not much a difference you can draw between a Sensor & a transducer, as both does the same thing of measuring an energy in form & converting it to other form. But a transducer will make an additional effort to convert the energy into measurable electrical form & then then transmitting!!!! Pls coment
It's a device that can convert energy of one form into another efficiently. Like a lightbulb for example, an energy efficient one would use less electricity but still produce as much light as one that is less efficient. It's a measure of what you get out versus what you put in.

energy = power x time.In this case, you can either: * Convert the time to seconds, then multiply. The answer will be in watt-seconds = joules. * Convert the time to hours, convert the watt to kilowatt, then multiply. The answer will be in kilowatt-hours.

Because of the second law of thermodynamics, which states that each time energy is converted from one form to another, some of the energy is always degraded to a lower quality, more dispersed, less useful form and that no system can convert energy from one form to another useful form with 100% efficiency.
