On a typical light microscope, the low power objective lens will be shorter than the high power objective lens.
The field for the high power objective is very small, so if you do not have the organism or whatever you want to view in focus on a lower power, it may be very difficult to find on high power. Also, the lens for the higher power objectives are longer than the lower ones, which makes them closer physically to the slide that you are viewing than the lower objectives. Thus you must use the fine tuning knob to sharpen the image in high power, because you could break the slide if you use the course adjustment knob.
The size of the cell remains the same no matter what power objective is used. However, the magnification changes between these two objective lenses, with the low power objective magnifying it less than the high power objective.
When using a microscope, you are magnifying the area under the lens by however many times the magnification is on your lens. On low power the area expanded by the lens is smaller than on high magnification. When on low power more is visible and there is less area to search for your given object under the microscope. I recommend finding the object on low magnification, and then switching to high once you have found it.
Not all microscopes have the same magnification for the lower power lens.

The high power objective is used to zoom in a little bit more than the low power ob
With a high power objective you see less sky and might not know where you are looking. With a low power objective you see more and it is possible to orient yourself among the objects in view.
Low power objective magnifies the object by 10 times, whereas high power objective magnifies 40 times. When we change from low power to high power, the object appears larger, exactly 4 times larger than low power. Low power objective covers a larger area, whereas high power covers a smaller area.
b/c the high power only allows you to see a small portion of thee slide. where as the low power pretty much allows you to see the whole slide all at once.
the difference between the low power and high power objectives on a microscope are that the low power objective has a lesser magnification than the high power objective

how much larger than normal does an object appear with lower power objective?
when you change from low power to high power the light intensity decreases. this is because the high power objective lens is smaller than the low power lens. therefore, the high power lens lets less light through
