What are transistors used for in a mobile phone? They store an electric charge. They store data. They amplify the phone’s incoming signal. They maintain proper voltage.

There are 2 types of Transistors:

But there are billions of transistors used in mobiles for their different functions such as voice signal processing or camera image processing

I hope you get the answer :)

what experimental evidence led scientists to change from the previous model to this one?

a few of the positive particles aimed at a gold foil seemed to bounce back.

the colors of light emitted from heated atoms had very specific energies.

experiments with water vapor showed that elements combine in specific proportions.

cathode rays were bent in the same way whenever a magnet was brought near them.

the components of a vector are the parts of the vectors that are to each other.
