Pls guys I have this standing fan in my apartment the reading says
220-240V
45w
50Hz
Pls help I need to know the amp reading
Because volt*amp=watt
And amp =Watt/Volt

But here the volt is 220-240, I dont know how to go about it because it is not on 12/24V

Amps=Watts/volts. So 45/220=.204 amps. At 12 volts, you'll need 3.75 amps to get 45 watts (45/12=3.75)

In Nigeria is it:
  1. 220-240 on one wire?
  2. 110-120 on each wire?
  3. Something else?
In cases 1 & 2 a clamp AC multi-meter on one wire should yield the amperage.
If you just are interested in calculating the amperage from the label that is 45/230=0.196 amps RMS

Thanks bro

This formula you wrote is correct.
Watt/volt = amps.
It doesnt matter what the voltage is, the formula is the same.

Watts are a constant of electrons...
Voltage is the pressure.
Amps are the work... or resistance...

All are derived from each other.
If you know ANY two parts, the third is just a calculation away.
 
So rounding up it is .21 amps...
That is just over 2 TENTHS of one amp... not much of a load.
