V = IR
I = V/R
According to the above formula, the electric device will ONLY record more current in HIGH VOLTAGE and LOW RESISTANCE.
***The guy above obviously has NO idea what he's talking about. "power = current x volt current"? That doesn't mean anything.

Yes. You can easily determine this is true based on the formula for Power. Power = Current X Volts. Current = Power/Volts. Less volts = more current draw to get the same power.
1200/110 = 10.9 amps.
1200/60 = 20 amps.
A little example to clear things up. I have two table saws on two different circuits. An ammeter is present in each circuit. Table saw 1 requires 220V. Table Saw 2 requires 110V. Both table saws are 1500 Watts.
Which ammeter will have the lowest reading when the saws are running?
What is the resistance in Ohms in each case?
What is the reading on each ammeter?
**THe question is incomplete as said below. I made assumptions and posed a scenario for it.

The question doesn't make sense. A current meter measures current. It doesn't care what voltage is pushing the current along.
