Materials that don't carry electricity at all are called insulators. Materials that can barely carry electricity are poor conductors. Gold, silver, and copper are among the best conductors. Aluminum is not as good a conductor as copper, but it was used in electrical wiring for years and is still found in places. Carbon is not that good of a conductor, but it has its uses, mostly in carrying signals short distances or for making resistors in electronics. Nickel, chrome and tungsten are poorer conductors, and that is why they are used for producing light and heat.
Yes, electrons carry electric current when they flow through a conductor such as a wire. The movement of electrons is what generates the flow of electric charge known as an electric current.
Yes, plasma can conduct electric currents because it is made up of charged particles (ions and free electrons) that can carry electrical charge and thus allow for the flow of current. Plasma is considered an electrically conductive state of matter.
No, permanent magnets are not produced by electric currents. They are made from materials that are magnetized and retain their magnetic properties without the need for external electric currents.
The 3 phase electric power is very common way of electric power transmission. Three circuit conductors carry three alternating currents the first conductor as reference the other currents are delayed in time for 1/3 and 2/3 of the cycle of the electrical currents.
The letter "I" is typically used to represent electric currents in equations.

Electric currents
Power resistors are designed to carry high electric currents due to their ability to dissipate heat effectively. These resistors are commonly used in applications where high power levels need to be handled, such as in power supplies, industrial equipment, and power electronics. They often have a large physical size and are built to withstand the heat generated by the current passing through them.
