we can stepdown the voltage from 230/12v ,and we use the
voltage for various electronics components why can't we
step up the voltage from 12/230v if we can shall we use the
voltage for domestic single phase supply

Answer Posted / michael

we can step up 12v to 230v but we cant use it for domestic single phase supply . we all know that V1/V2 = I2/I1
the amount of current comes from electronics device will be lower when we use step up again the voltage to 230v. you will attain the 230v but not the current needed by the equipment

A 15 kw squirrel cage motor having a maximum efficiency of 90% on a continuous full load has temperature rise of 42 degrees celcius after 30 min and 52 degrees celcius after 1 hr under the above operation conditions. a) calculate its final steady state temperature rise on continuous load and the heating time constatnt. b) if the motor is operated on a short load for 9 min estimate its temperature rise. c) calculate the maximum overload that can be applied on a short, 9 min rating so that the temperature rise is the same as the final steady state temperature rise on continuous load.
