Plz provide the answers in points.. I need it for my school seminar assignment.
DC generators 1. Best for charging batteries for electric vehicles and rechargeable batteries in all portable devices. 2. Used to run electric drive motors in industrial machinery because DC motors have easier and more precise speed control than AC motors 3. DC generators used to run traction motors in diesel locomotives. 4. Used to run DC welders for specific kind of welding 5. Used to run electrolysis and electrowinning of metals from solutions. --------------------- AC generators --------------------- 1. Used to generate all of the electricity we use in households and businesses. AC has a lot less line losses than DC so is universally used worldwide to supply electricity 2 Used to run transformers which allow the stepping up or down of voltage and current. DC can't do this. 3. Used to run three phase electric motors which are much cheaper than DC motors and provide more available horsepower per pound of motor over DC. 4. Cheaper per kilowatt-hr and delivery charge of power than DC.
