Question
If the hair dryer and vacuum cleaner both are switched on, what is the power used?
- 2600 W
- 400 W
- 1500 W
- 1100 W
Hint:
The power consumed by an appliance is depicted by its power rating.
The correct answer is: 2600 W
The hair dryer is rated at a power of 1500 W.
The vacuum cleaner is rated at a power of 1100 W.
The total power used when both of these appliances will be switched on will be the arithmetic sum of their power ratings.
Thus, total power used = 1400 + 1100 = 2600 W.
Hence, option (a) is correct.
