Explain why static charge not produced by rubbing metals Static charge is not produced by rubbing metals because metals are poor electrical insulators, meaning that any charge that is generated is quickly dissipated due to the conductivity of the metal. When two non-metallic materials are rubbed together, the electrons move from one material to the …

How to protect ourselves when there is a lightning Stay indoors and away from windows, doors, and porches during a thunderstorm. Unplug all electronics and turn off or unplug any appliances. Avoid contact with concrete walls or floors, and metal objects such as pipes, sinks, and radiators during a storm. If you are outside, do …

A lightning conductor is a device designed to protect a structure from lightning strikes by providing a path for the lightning’s electric current to safely pass into the ground. It consists of an insulated wire or metal rod, connected to the ground through a low-resistance connection, usually a metal rod that is inserted into the …

Thunder and lightning are both natural phenomena that occur when atmospheric conditions cause an electrical discharge in the atmosphere. Thunder is the sound created by the shockwave of the lightning event and is caused by the rapid heating of the air around the lightning bolt. Lightning is an electrical discharge between the clouds, the air, …

Distribution of electric charge The electric charge distribution can be determined from the electric field produced by the system of particles. The electric field is a vector field which, at any given point in space, indicates the direction and magnitude of the force that would be experienced by a charged particle placed at that point. …

A capacitor is capable of storing energy in the form of an electrostatic field. This is done by having two metal plates separated by an insulating material, such as a dielectric. When a voltage source is connected to the capacitor, it stores a charge on each plate. This charge creates an electric field between the …

Electrostatic induction Electrostatic induction is the phenomenon in which a charged object causes a change in the electric field of a nearby neutral object, resulting in a separation of charge on the neutral object. This can be either an attraction or repulsion of the neutral object’s charges, depending on the type of charge on the …

Earth is a naturally occurring conductor and so it is commonly used to provide a reference for electrical circuits. This reference is known as grounding or earthing. In electrical systems, grounding or earthing provides a path for stray currents and other electrical disturbances to flow to the earth. Grounding also helps protect equipment from electrical …
