An digital camera has seven parts; the shutter release, light path, view finder, Sensor, shutter, mirror, and the aperture. the the shutter-release button is a push-button found on many cameras, used to record photographs. the light path but in between the lens and the shutter lies a mirror that blocks the light from reaching the shutter. The view finder is just a small part of the camera that allows you to look at what you wanna take a picture of. The sensor is a solid-state device which captures the light required to form a digital image. the Mirror of the digital camera allows light to enter a single lens where it hits a mirror that reflects the light either upwards or downward into the camera’s viewfinder. last but not least the aperture allows you to turn it so that you can zoom in or zoom out in the camera to snap a photo.
A digital camera takes light and focuses it via the lens onto a sensor made out of silicon. It is made up of a grid of tiny photosites that are sensitive to light. Each photosite is usually called a pixel, a contraction of "picture element". There are millions of these individual pixels in the sensor of a DSLR camera.
Answer: There's no long-distance energy transfer. This looks almost like a plain old transformer (yet with an air core) and I've never heard of a 7 kilowatt transformer wasting as much as 14 percent energy in conversion - dissipating about one kilowatt of power would just melt the transformer. How realistic is the "86% efficiency" claim?
Objective tests are measures in which responses maximize objectivity, in the sense that response options are structured such that examinees have only a limited set of options
