You have to adjust it to maximize contrast. If you have too much light, you won't have much contrast between the object and the background.
The increase in magnification cause a decrease in the field of view.

Increasing the brightness or adjusting the contrast settings on the microscope can help increase image contrast in low power magnification. Additionally, using a higher quality objective lens or adjusting the illumination angle can also enhance image contrast.
As you change objectives from 4x to 10x to 40x, the field of view will decrease. This is because higher magnification objectives bring smaller areas into focus, resulting in a narrower field of view.
Compressing the inferior vena cava below the diaphragm can decrease venous return to the heart, leading to reduced preload and consequently a decrease in cardiac output. This can result in decreased blood flow to the rest of the body and potentially lead to symptoms like lightheadedness or hypotension.

The torque applied to the drive is adjusted by instructing the engine to increase or decrease output.
The amount of light needed increases as one moves to higher magnification with the microscope. This is because higher magnification levels result in smaller fields of view, requiring more light to illuminate the specimen effectively.
When exhaling, the diaphragm relaxes and moves upwards, causing a decrease in the volume of the chest cavity. This increase in pressure pushes air out of the lungs.
The diaphragm causes an increase in thoracic volume. When the diaphragm contracts and moves downward, it creates more space in the thoracic cavity, allowing the lungs to expand and fill with air during inhalation.
The depth of field decreases.
The objective lens and the ocular lens both work together to increase the magnification in a microscope. The objective lens is responsible for gathering light and forming an initial image, while the ocular lens further magnifies this image for viewing.
A hydraulic piston can be used to increase force by applying hydraulic pressure to the piston, which amplifies the force output. To decrease force, the hydraulic pressure can be released or adjusted to decrease the force exerted by the piston.
