Electrical properties refer to how materials respond to electric fields and currents. These properties include conductivity, which measures how easily electricity flows through a material, and resistivity, which indicates how much a material opposes the flow of electric current. Conductors, like copper and aluminum, have high conductivity, while insulators, such as rubber and glass, have high resistivity. Another important electrical property is capacitance, which is the ability of a material to store electrical energy in an electric field. Capacitors, devices that store energy, utilize this property. Additionally, the dielectric strength of a material indicates how much electric field it can withstand before breaking down, which is crucial for safety in electrical applications.
