Of course it does not use one bit of current. Pencil sharpeners have a switch that activates the current. When it is being used, it uses about .05 of an Amp. When not in use, there is zero current being used, even if plugged in. This is the same for an office stapler, etc.
Hope that helps!

No, it is not recommended to sharpen a pencil with paper still attached to it as it may damage the pencil sharpener and prevent the pencil from being sharpened properly. It is best to remove any paper or plastic wrapping before sharpening a pencil.
The handle (wheel) moves a greater distance than the sharpening mechanism (axle). The handle exerts greater force as it must overcome the resistance of the pencil being shaved and the friction in the sharpener.

Sunlight is converted to electricity through solar panels, which could then power a knife sharpener. The solar panels capture the sunlight's energy and convert it into electrical energy, which is then used to power the knife sharpener's motor, resulting in the sharpener being powered by sunlight indirectly.
A pencil can be considered a Class 3 lever, with the hand providing the effort, the pencil acting as the load, and the fulcrum being where the hand grips the pencil.
You know what why you being a pencil sharpener? If you are young read this. A pencil sharpener is a man and a woman in a room naked and the guy has a boner and sticks it in the girls mouth.
It helps you sharpen your pencil so you can write with it again without it being dull.

September 26, 1889John Lee Love - Improved Pencil SharpenerJohn Lee Love's invention was a very simple and portable pencil sharpener. The same kind of pencil sharpener that many artists use or that can be found in an office or school room. In John Lee Love's invention the pencil is put into the opening of the sharpener and rotated by hand. It was designed so that the shavings would stay inside the sharpener. It is interesting to note that while the patent drawing depicts the Love Sharpener as being quite plain. John Lee Love wrote that it could also be designed in a very ornate fashion and that his pencil sharpener could also be used as a desk ornament or paperweight.Johm Lee Love's pencil sharpener was patented on November 23, 1897 (U.S. Patent # 594,114).John Lee Love - Improved Plasterer's HawkFour years earlier, John Lee Love created and patented his first invention an improved plasterer's hawk. A plasterer's hawk is a flat square piece of board made of wood or metal, upon which plaster or mortar was placed and then spread by plasterers or masons. Love felt that other plasterer's hawks were too bulky to be portable so he designed one with a detachable handle and a foldable board all made from aluminum. John Lee Love's improved plasterer's hawk was patented on July 9, 1895 (U.S. Patent #
An unknown inventor, probably 2 500 years ago, in the ancient Roma. Having been lost for centuries, it was independently discovered again in the late 19th century in Nevada, USA, by Joseph Cartwright. Cartwright and his business partner, Joseph Dixon, commericalized the product by embedding it inside of wooden sticks cut from the numerous pine trees on Cartwright's ranch. The Dixon-Ticonderosa pencil was thus born and sold throughout the western United States, and it remains a strong player in the global pencil industry to this day.

The number two in reference to a pencil denotes the relative hardness of the graphite or "lead" that is in the pencil, HB being softer and three being harder, etc.
Yes, it does. The current is still flowing through it, although there is nothing being charged.
A pencil can be considered a Class 3 lever, with the hand providing the effort, the pencil acting as the load, and the fulcrum being where the hand grips the pencil.
There is no such unit of measurement as a pencil.
