What element of the periodic table is used in cellphone?
Mercury is commonly used in the batteries of cell phones and laptops.
Do gamma rays have higher frequencies than radios?
Yes, on the order of 1013 hertz higher.
What are two uses of electromagnetic radiation in your world on earth?
we use electromagnetic waves in radios and cell phones
What different kinds of media make up the press?
Audio,text,graphics,animation and motion videos etc.
Can you plug a CB radio into a standard wall outlet?
They do make base station CB radios, which run off of 120v AC power.
What do you call the vacuum tubes used in transistor radios?
You don't, there aren't any. However some radios in the early 1950s did use both vacuum tubes and transistors. This was because early junction transistors were too slow to operate at RF so vacuum tubes were used in the RF and IF sections. These radios were called hybrid radios because they used both vacuum tubes and transistors.
Does a cathode ray tube resemble the tubes used in transistor radios?
Transistor radios have NO tubes. They have (guess what) transistors.
Which three electronic devices contain transistors?
Radios, Televisions & Computers.
What do radios have to do with wireless sound?
Radios have to wireless sound because more radios exspeshualy in the present days are wireless they have no cord or plug for them to work you just push a button then then you have sound.
How can an integrated circuit signal info?
Items such as radios and transistors use integrated circuit signals. They send signals by opening and closing electrical circuits in sequence.
What electronic devices contain transistors?
Practically everything. Even devices using electron tubes (e.g. microwave cookers, high power radio and TV transmitters) now generally use transistors to control the tubes.
Would 2 way radios make a good present for children?
Two way radios are a wonderful choice of present for children. It encourages them to play outside and to engage in pretend play which is beneficial to their development.
What radioactive element may be used in luminous paint radios and guided missiles?
Promethium
How many transistors are in a radio?
Depends on the radio. Early Transistor radios started with just one and it was to replace the valve which was in turn used for signal amplification. Today, a sophiticated radio may have several chips inside them that can contain millions of transistors each. There is no absolute definitive answer to this question.
What are the radio elements define with their name n symbol?
We can not display symbols for electronic components on WikiAnswers, but the elemental components from which radios are made are transistors, resistors, capacitors, wires and speakers.
How do they make radios?
Most radios begin with a printed circuit board- metallic copper printed onto a fiberglass board- this will be most of the wiring. A computer controlled machine "stuffs" the holes in the circuit board with transistors, capacitors and resistors, and they are all soldered in place at one time.
What did people use to watch or hear the baseball games when there were no TVs?
When there were no televisions, people either went to the games or listened to them on the radio. There was no other way to watch the games than to be there. There were photographs in newspapers, however. The radios in those days were monsters in terms of size. They used vacuum tubes since transistors were not invented yet, and they used expensive banks of batteries to get the voltages needed for the tubes. Newer tube radios were able to use line voltage. Then as transistors came along, the size of radios began to dramatically decline and even become portable.
