1. The DC generaror,s induced output emf is connected with a DC motor(as load). when increasing the load of the motor by using brake drum or any way. what are the parameters will changes in both motor and generator(voltage, current, resistance, frequency, speed, torque, power, flux etc...) 2. Similarly for AC generator and AC motor 3. similarly if using DC batteries instead of DC generator, What happens?

Hello everyone, somebody knows what is a "surplice power" ? The hole phrase is: "This rating is appropriate for a generator set paralleled with an infinite bus e.g. a national electrical supply network or grid where the generator set is run at 100% load, 24 hours a day, 365 days a year and any surplice power is exported into the grid" Thanks in advance.
