Explain the mechanism of motor |
|
Answer» Lg rha h aadhi book yhi chaap di h Bacche ki jaan le li An electric motor is an electrical machine that converts electrical energy into mechanical energy. The reverse of this is the conversion of mechanical energy into electrical energy and is done by an electric generator, which has much in common with a motor.Most electric motors operate through the interaction between an electric motor\'s magnetic field and winding currents to generate force. In certain applications, such as in regenerative braking with traction motors in the transportation industry, electric motors can also be used in reverse as generators to convert mechanical energy into electric power.Found in applications as diverse as industrial fans, blowers and pumps, machine tools, household appliances, power tools, and disk drives, electric motors can be powered by direct current (DC) sources, such as from batteries, motor vehicles or rectifiers, or by alternating current (AC) sources, such as from the power grid, inverters or generators. Small motors may be found in electric watches. General-purpose motors with highly standardized dimensions and characteristics provide convenient mechanical power for industrial use. The largest of electric motors are used for ship propulsion, pipeline compression and pumped-storage applications with ratings reaching 100 megawatts. Electric motors may be classified by electric power source type, internal construction, application, type of motion output, and so on.Electric motors are used to produce linear or rotary force (torque), and should be distinguished from devices such as magnetic solenoids and loudspeakers that convert electricity into motion but do not generate usable mechanical powers, which are respectively referred to as actuators and transducers. |

How does day and night happen? |
| Answer» The Earth is a sphere, or ball, which spins round and round as it travels around the sun. One side of the Earth faces the sun, while the other side faces away into space. The side facing the sun is bathed in light and heat—we call this daytime. The side facing away is cooler and darker, and experiences night. Because the Earth is constantly spinning, the line between day and night is always moving around the planet. A day on Earth lasts 24 hours—that is how long it takes for the planet to spin around once. | |
