When using an electric razor, what should you be aware of?

When using an electric razor, it is crucial to be aware of power, sharpness, and heat for safe and effective usage. The power of the razor refers to ensuring it has a proper charge or is connected to a power source to function correctly. Sharpness indicates the condition of the razor blades; dull blades can cause discomfort or injury during shaving. Heat is an important factor as electric razors can generate heat during use, leading to discomfort or skin irritation if the device is not monitored.

The other concepts that may have been included in the other options, such as water or cleanliness, are not relevant when specifically considering electric razors, as they typically do not require water like traditional razors and do not necessitate the same level of cleanliness considerations during operation. Safety is always a priority with any electric device, but the specific aspects of power, sharpness, and heat are the most pertinent in the context of using an electric razor.
