When an electric heater is turned on, electrical energy is converted into heat energy. The electricity flows through the heating element, which has high resistance, causing it to heat up and produce heat. This heat is then transferred to the surrounding air, raising the temperature in the room.
An example of electrical energy changing to heat energy is when an electric heater is turned on. The electrical energy powers the heating element in the heater, which then converts the electrical energy into heat energy that warms up the surrounding area.
When an electric light is turned on, electrical energy is converted into light energy and heat energy. The electrical energy powers the light bulb, causing it to emit light. Some of the electrical energy is also transformed into heat energy due to the resistance within the light bulb.
The form of energy represented by x when an electric fan is turned on is electrical energy. This is the energy that powers the fan and is converted into mechanical energy, which allows the fan blades to rotate and create airflow.
Electric energy to kitenic energy
Answer #1: mechanical==========================Answer #2:Kinetic energy of the moving air, and heat in the motor.
Mechanical energy
the form of energy changes and the total of energy increases
An example of electrical energy changing to heat energy is when an electric heater is turned on. The electrical energy powers the heating element in the heater, which then converts the electrical energy into heat energy that warms up the surrounding area.
The water heater is turned off to save energy and prevent overheating or potential damage.
When an electric light is turned on, electrical energy is converted into light energy and heat energy. The electrical energy powers the light bulb, causing it to emit light. Some of the electrical energy is also transformed into heat energy due to the resistance within the light bulb.
Mechanical energy.
Heat then - into Electric energy
The form of energy represented by x when an electric fan is turned on is electrical energy. This is the energy that powers the fan and is converted into mechanical energy, which allows the fan blades to rotate and create airflow.
Yes, it is recommended to turn off the water heater when the water is turned off to prevent damage to the heater and save energy.
No. they use chemical energy, that gets turned into mechanical energy, that gets turned into electric energy.
gas
Efficient, yes. But a poor choice for a heater. It's just a marketing gimmick. Every electric heater is nearly 100 percent efficient. Efficiency is a term not understood by many. Energy efficiency - useful work per quantity of energy. In other words, What is the job of an electric heater? To make heat. How much of the electricity fed to the heater is turned into heat? All of it. That makes it 100 percent efficient. In contrast an incandescent light bulb is only about 5 percent efficient, only 5% of the electricity fed to it is converted to light the other 95% is converted to heat.
