Many electronic devices contain a small amount of gold, especially on the circuit board. This is because gold is a highly efficient conductor (better than copper) and it does not corrode, ensuring therefore that no interruption occurs in transmitting voltages and currents needed to run the device.

How much gold is on a circuit board
Magann: A PC card whose gold weighs about a kilogram. If you have an avalanche of these boards, you should get Troy for 5 ounces of gold.
Can you get gold from circuit boards
All of the circuit boards involved have gold in them – laptops, phones, cameras, and other devices use the precious metal to connect components, and software is relatively easy to mine.
What part of the circuit board has gold
Motherboards and pieces of wood used for circuit boards. In particular, motherboards tend to be the best potential source of gold in computers. The edges of many components on the board are made of yellow gold and have contacts and terminals into which wires are inserted. Sometimes thin layers of gold can be found on the surface of the motherboard.

Why is a series resonant circuit called an acceptor circuit & parallel resonant circuit is called Rejecter circuit
Because a sectional resonant circuit only works when it is in resonance, this type of circuit is designed as an acceptor circuit because at overresonance the impedance of the program is so small that it immediately accepts a current whose frequency is just equal to its resonant frequency.
Why the series resonance circuit is called an acceptor circuit and the parallel resonance circuit is called Rejector circuit
Himanshu said this. A series resonant circuit can be called an acceptor circuit because although the applied voltage can be made up of any number of frequencies, the signal should only accept the maximum current due to the resonant frequency and reject all other frequencies.
What is a circuit breaker where are circuit breakers located What is the function of a circuit breaker
A circuit breaker is a separate electrical switch designed to protect a new, well-functioning electrical circuit from damage caused by overcurrent/overload or short circuit. Its main function is to interrupt the flow of current after the protective relays have detected a complete failure.
