Simple electronic circuits are used in simple electronic devices.
Before circuit boards, we used point-to-point wiring between components that were usually mounted onto a metal chassis or plugged in to sockets. It's a low-tech method still used in prototyping, for very small production runs and by hobbyists. Individual transistors developed into integrated circuits (chips), but these were still mounted onto some kind of circuit board/chassis. The advance was to integrate *very many* transistors (millions-plus) into Very Large Scale Integrated (VLSI) circuits, such as microprocessors and memory chips. So.... 1. A low-cost, short-run alternative is point-to-point wiring, 2. The high-technology alternative is to integrate many//most/all functions into a single ship.

'Apparent power' is a term used in a.c. circuits, NOT d.c. circuits.
A thermometer can be used to check the purity of a metal by measuring its melting or freezing point. Impurities in a metal can alter its melting point, so a pure metal should have a specific and consistent melting point. By comparing the measured melting point with the known melting point of the pure metal, the level of purity can be evaluated.
Tungsten is a metal with a high melting point that is often used in incandescent lamps.

The metal you are referring to is likely bismuth. Bismuth is commonly used in low melting point alloys due to its low melting point and is often found in pink due to its inherent color.
Bismuth
One common physical property used to test the purity of metal is its melting point. Impurities can lower the melting point of a metal, so comparing the measured melting point to the known pure metal can indicate the presence of impurities. Other techniques include density measurements, spectroscopy, and X-ray diffraction.
Gallium is a metal with a low melting point of 29.8°C. It is used in fire detection systems as its melting point is below room temperature, allowing it to be placed in heat-sensitive components that trigger alarms when the temperature rises above gallium's melting point.

because gold or iron are metal if they are not a metal so they can not check the purity but they are metals..
Titanium is a reactive metal with a high melting point that is used in the manufacture of rocket nose cones. Its combination of strength and low weight make it ideal for aerospace applications.
Beryllium is a metal. It is a lightweight, strong metal that is commonly used in aerospace and defense applications due to its high melting point and stiffness.
Hafnium is a metal. It is a transition metal that is commonly used in the production of nuclear reactors and in semiconductor manufacturing due to its high melting point and resistance to corrosion.
