Physics #2

Accelerated Christian Edu. PACE 1120, for CRT's, IC's, and transistors.

The CRT screen is coated with what? The inside of the CRT screen is coated with rows of tiny, phosphorescent dots.
Describe a modern CRT. The modern CRT is a specialized vacuum tube that's narrow at one end and flares into a wide screen at the other end.
What does the narrow end of the CRT contain? The narrow end of the CRT contains an electron gun which emits a narrow beam of high-speed electrons.
What components are inside the electron gun? Inside the electron gun is a cathode, a control grid, and two anodes.
The advantages of transistors over vacuum tubes are what? They don't require a warm-up period, are less expensive, do not burn out, and are smaller.
How many regions of semiconductor material does a transistor contain? Three regions.
In field-effect transistors, what controls current? Voltage applied to the gate controls current.
In junction transistors, what controls output current? Current controls output current.
Why are IC's easily mass-produced? IC's are easily mass-produced because they are less expensive than similar circuits using larger solid-state components.
