The efficiency of any machine is the output power divided by the input power, usually expressed as a percentage.

Why efficiency of generator is greater than motor?
i think both will be same..
What are advantages of swinburne's test?
we can predetemine the efficiency of a dc machines working as a motor or generator
Why generator has more efficient than motor?
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%.
Why generator has the better efficiency than motor?
becoz alternater has work on principle of electomagnetic induction .
What is swinburne's test of DC shunt motor?
swinburne's test on dc shunt machine is to predetermine the efficiency of the dc machine , but it is not accurate it is just like estimation of efficiency of dc shunt machine when it is run as a motor and a generator............................
Why the efficiency of generator is more than the motor in case of swinburne's test?
the generator windings are made of more thicker windings . Hence lesser resistance and lower Cu losses
AC motor and generator with complete technical analysis and calculations of efficiency different types pf technological advancements?

What is the problem with using an electric motor to run a generator stepped up with transformers that is used to run the motor and give electricity for other uses?
It's all to do with the conservation of energy. The output power of the transformer cannot be greater than the input power from the motor used to drive your generator! In fact, it will be significantly lower than the power of your first motor due to the efficiency of the motor, of the generator being driven by that motor, and of the transformer. So if you then try to run the original motor from the output of your transformer, the energy-losses will simply accumulate, and the motor will not be able to run!
Why load angle is positive for generator and negative for motor?
simply put a motor consumes power and a generator produces it. reactance of a generator = - reactance of a motor
Can a motor operate as generator?
Yes, by giving mechanical power to motor . It acts as a Generator.
Did Mike Faraday invent the generator and motor?
Mike Faraday did invent the generator and motor.
How does ac electric motor convert in to an alternator?
a motor is a generator and a generator is a motor, if you are applying a voltage to turn the rotor its a motor and if you are turning the rotor and taking the voltage off the terminals its a generator or alternator.
