To determine the current being used by the vacuum cleaner, we can utilize Ohm's Law, which states that Power (P) equals Voltage (V) multiplied by Current (I). The formula can be rearranged to calculate current as follows:

I = P / V.

In this case, the vacuum cleaner has a power consumption of 1000 watts and operates at a voltage of 240 volts. Plugging in these values, we calculate:

I = 1000 W / 240 V = 4.17 A.

Thus, the correct answer is indeed 4.17 amps. This indicates how much electrical current the vacuum cleaner draws while operating at its maximum power consumption. Knowing this is crucial for understanding the electrical load it places on a circuit and aids in assessing whether the existing wiring and breakers can handle this load without risk of overheating or tripping the circuit breaker.
