Probably because brass is generally tarnish resistant /doesn't discolour so easily
Although brass is not as conductive as silver, copper, and aluminum it is less expensive to make and generally easier to work with.
Pins are typically made of metal, such as steel, brass, or copper. The choice of metal can vary depending on the intended use of the pin, with factors like durability, appearance, and cost influencing the selection. Some pins may also be made of plastic or other materials.
Some pin plugs are mostly seen with three pins. The two pin plugs being flat, equal, and has a hole because this is where electricity flows. The round pin plug is used to absorb more flow of electricity for example computers and laptops have round pin plugs because it needs a lot of electricity, the round pin plug is only cut when using a device that doesn't need to much electricity to work.
Tt depends on the metal which is the cathode and which is the anode. However, in most cases, graphite is the cathode and the metal is the anode. the strictly correct answer is that BOTH the metal and the graphite rod are electrodes. You must have two electrodes minimum to create a cell.
Metals are used in an electroscope because they are good conductors of electricity. This allows the electroscope to easily detect and respond to electric charges. Metal materials also provide durability and stability to the electroscope's components.
Yes, because to conduct electricity you need a metal wire, (usually copper). However they have a plastic outer coating (sheath) which protects them and insulates them.
The type of electric plug commonly used in Brazil is the Type N plug, which has two round pins and a grounding pin in a triangular formation.
A metal pen of an electric plug is a conductor. Metals like copper, aluminum, and steel are good conductors of electricity due to their ability to easily allow the flow of electrons. This is why metal is commonly used in electrical wiring and components.
Orthopedic surgery often uses metal pins. The materials used in these pins (and other hardware) include stainless steel and titanium alloys.
The plug type used in Japan is Type A, which has two flat parallel pins. This is different from the plug type used in the US, which is Type A or Type B, with two flat parallel pins or two flat parallel pins and a round grounding pin, respectively.
Metal often used to make Christian lapel pins is zinc. These types of pins can also be made from pewter or gold-plated silver. Some pins are constructed from nickel too. The cost of the pin will in part be based on what kind of metal is used to make it.
steel

The type of wall plug commonly used in Chile is the Type C plug, which has two round pins.
The type of electric plug used in Ireland is the Type G plug, which has three rectangular prongs in a triangular pattern.
The type of electrical plug used in Brazil is the Type N plug, which has two round pins and a grounding pin in a triangular formation.
The type of plug used in India for electrical appliances is the Type D plug, which has three round pins in a triangular pattern.
The type of power plug used in Brazil is the Type N plug, which has two round pins and a grounding pin in a triangular formation.
