1200 watts / 120 volts =10 amps begins to flow as soon as you plug it in.

Answer: The current of value 10 ampere runs through the vacuum.

Explanation;

Power of the water heater = 1,200 watts

Voltage applied to the water heater = 120 V

Duration of the use of water heater = 1.5 seconds

[tex]Current=\frac{Power}{Voltage}=\frac{1,200 W}{120 V}=10 ampere[/tex]

The current of value 10 ampere runs through the vacuum.
