Try to analyze the energy conversion between wind power for home lighting, if there is no energy loss, what will happen
Wind energy -- mechanical energy of fan blade -- mechanical energy of generator rotor -- electric energy -- light energy (and internal energy)
Finally, whether there is internal energy depends on the lamp. If there is incandescent lamp, there is almost no diode
If there is no energy loss, human beings basically don't have to consider the energy problem. Nowadays, the efficiency of heat engines can hardly exceed 50%, only the engine of jet aircraft can reach about 60%; the power consumption is slightly better, but there is no way to go, if the efficiency can reach 100% Heaven
Now small wind turbines have entered the family Electric energy is energy (fill in "primary" or "secondary") why is the answer secondary energy_
Now small wind turbines have entered the family Among them, electric energy is - (fill in "primary" or "secondary") why is the answer secondary energy? Does it not only convert mechanical energy into electric energy? Solar cells convert solar energy into electric energy, which electric energy is not primary energy? What's the difference between the above two?
Hehe, primary energy, refers to the original form of existing in nature, unprocessed energy resources. Also known as natural energy. Wind power, wind energy is the most primitive energy, this is the primary energy, electric energy is converted from wind energy, become secondary energy
The battery must be the power supply in the circuit,
It's right to convert chemical energy into electrical energy
And when you charge, you convert electrical energy into chemical energy
A power source, such as a battery generator, is an electrical energy device in a circuit
Hehe, the power supply in the circuit is a device (to provide electric energy), and the consumer is a device (to consume electric energy). The switch plays a role in the circuit (to control the circuit on-off)
I hope my answer can help you~~~

- 1. How can inductors convert the stored magnetic energy into electrical energy and send it back to the power supply? The pure inductor does not consume energy. In the first and the third quarter cycle, P is positive, and the capacitor takes electric energy from the power supply and converts it into magnetic energy, which is stored in its magnetic field; in the second and the fourth quarter cycle, P is negative, Inductive elements convert the stored magnetic field energy into electric energy and send it back to the power supply. How can inductive elements convert the stored magnetic field energy into electric energy and send it back to the power supply? Also, if the pure inductance does not consume energy, where does the electromagnetic torque come from? Because the stator winding of the motor is also pure inductance, Electric energy is converted into magnetic energy, and then magnetic energy is converted into electric energy. How can there be electromagnetic torque output?
