0.5 Wh of electrical energy is equivalent to 1.8 kJ (kilojoules) of energy. This amount of energy would be converted into heat energy by an electric heater or device that produces heat.
The amount of heat energy produced from electrical energy depends on the efficiency of the system. If we assume 100% efficiency, then all 3000 joules of electrical energy would be converted into heat energy. Thus, 3000 joules of electrical energy would produce 3000 joules of heat energy.
That depends on how long the 1 kW is applied. Please note that kW is a unit of power, not a unit of energy.In general, 1 kW of electrical energy can be converted into 1 kW of heat - if used in a heater. With a heat pump, 1 kW of electrical energy can, in fact, pump several kW of heat energy.
If 92 J of electrical energy are converted into 92 J of mechanical energy in an electric motor, then all of the electrical energy is being converted into mechanical energy. No thermal energy is being produced in this scenario. The efficiency of the motor in this case is 100%, meaning all the input energy is being converted into useful work without any energy loss in the form of heat.
The amount of energy produced by electrical energy depends on the source of the electricity. For example, a wind turbine or solar panel will produce a certain amount of energy based on their capacity and efficiency. The energy produced can be calculated in kilowatt-hours (kWh) or joules, depending on the context.
Yes, resistance in a conductor causes energy losses due to heat. Metals such as Gold and Platinum have very low resistance but they are very expensive so Copper and Aluminium are used instead which are much more affordable but have higher resistance.

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.
100% of the electrical energy flowing through the copper wire is transformed into mechanical energy if no energy is lost as heat and no electrical energy remains after running through the coil. This scenario implies ideal efficiency in the conversion process.
2,598,000,000,000 kWh a year, that was estimated in 2008.
In a LED, electrical energy is converted directly into light energy, resulting in a decrease in electrical energy and an increase in light energy. This process is much more efficient than traditional incandescent bulbs, which waste energy as heat.
No, not all energy is lost as heat. In many systems, energy can be converted into other forms such as mechanical energy or electrical energy, rather than solely being dissipated as heat. The efficiency of a system determines how much energy is lost as heat versus how much is converted into useful work.
