Parfocal
depending at the kind and high at the voltage, or/and the high of the power
Parfocality is the term used to indicate that when an object is in focus at low magnification, it will also remain in focus at higher magnifications without the need for refocusing.
The fine adjustment knob is used to bring the image of an object on the slide into focus when under the high power objective lens. This knob allows for precise focusing by making small adjustments to the distance between the objective lens and the specimen on the slide.
Watts are commonly used to measure power generated by an object.
Power transistors are transistors that are used in high-power amplifiers and power supplies.
A higher power objective lens in a microscope is used when greater magnification is needed to study an object. The higher power objective lens has a shorter focal length and needs to be closer to the object being studied. It has a smaller aperture (lens diameter) so it has a narrower field of vision and may require more light to be useful. This means that it is more difficult to find and center the item being studied under the lens and it is harder to focus the lens on the object.
The high power objective is used to zoom in a little bit more than the low power ob
low-power magnificatin = (10x)(4x) = 40x high-power magnification = (10x)(40x) = 400x It depends on what magnification you are looking for; high-power magnification OR low-power magnification.
High voltage power supplies have many uses. It is most commonly used to supply power from a device to the circuit. These are great for people who need to supply their house with power.
