no need to ask any one.
you can do the experiment your own.
just measure the voltage drop accross LED in your circuit (it will be 1.2 to 1.7 V)
now measere the current flowing through LED (it will be few (10 – 15) mA)
your power consumption P = V I
same can be applied to all devices
for example stepper motor.
if you have data sheet of the motor u have find out current / phase
and operating voltage.
multiply this you will get power consumption / phase
then add all power for each phase.
