power in equals power output plus power loss so input power for this question is 100 kw now use efficiency formula 100/80 times 100 to get 80% efficient
In an electric motor, electrical energy is converted into mechanical energy to produce motion. In a generator, mechanical energy is converted into electrical energy by rotating a coil within a magnetic field. Essentially, electric motors convert electrical energy into mechanical energy, while generators convert mechanical energy into electrical energy.
The rate at which electric energy is converted to another form is measured in watts (W) or kilowatts (kW). This conversion rate depends on the efficiency of the device or system that is transforming the electric energy into another form, such as heat, light, or mechanical energy.
The efficiency of an electric generator is influenced by factors such as the design of the generator, the quality of its components, the speed at which it operates, and the temperature at which it runs. Other factors include the type of fuel or energy source used, maintenance practices, and environmental conditions.
An electric motor converts electrical energy into mechanical energy to produce motion, while an electric generator converts mechanical energy into electrical energy by inducing a flow of electrons. In essence, a motor uses electricity to create movement, while a generator creates electricity from movement.
An electric generator produces electrical energy. It converts mechanical energy to electrical energy by interacting with a magnetic field. The amount of electrical energy converted to useful work in a given time interval is the power output. If the generator is not connected to any load, then no work is done and there is no power.
An electric motor converts electrical energy into mechanical energy. While an electrical generator does the opposite.
Depending on what you're referring to, you may have this completely backwards. A motor's efficiency is fairly high. A generator's efficiency at converting chemical/kinetic/mechanical energy to electric energy is at best around 50%.

Motor is device which converts electrical energy to mechanical energy,where as generator converts mechanical energy to electrical energy
An electric generator and an electric motor does the opposite!
It changes mechanical energy to electricity.
It changes mechanical energy to electricity.
An electric power generator is a generator the converts mechanical energy into electrical energy. That way you can get energy from the generator to produce electricity to places like your home.
A device that converts mechanical energy into electrical energy.
In electricity generation, an electric generator is a device that converts mechanical energy to electrical energy. A generator forces electric current to flow through an external circuit.
