Technology !.. The transition from transistors to integrated circuits meant that phones could be made physically smaller - while having more functions.
Cellular phones contain a variety of electronics circuitry. Along with the battery, there are lots of digital circuits, many of which are microprocessors or microprocessor controlled. There are a few "token" analog circuits that handle the incoming and outgoing audio. Additionally, there are a number of RF (radio frequency) circuits that handle do the transmitting and the receiving of the signals. Without getting too technical, that's the wrap.
AT&T digital home phones monitors your home alarm system. They will receive notices of suspicious activities in your home, such as a break in electric circuits. Yes, they are effective.
Flexible printed circuits are used so that boards can be conformed to a particular shape. They are often used in computer keyboards, cameras, calculators, and cellular phones.
Miniaturized electronics of all sorts- portions of TV circuits ( the Motorola Quasar) was an early example, Radios, calculators, computers, a bit more modern Cell Phones are absolutely dependent on these miniaturized devices used also in avionics and space technology for obvious space-saving needs.
The three types of electronic circuits are called closed circuits, open circuits and series circuits. You will often hear these terms when an electrician explains what he is doing.

Electricity appears in various forms such as lightning in the atmosphere, electrical circuits in homes and buildings, as well as in electronic devices like phones and computers. It plays a fundamental role in powering modern technologies and infrastructures.
a "LC circuit at resonance" and tuned circuits are the same
The types of circuits are series and parallel!
