Natural frequency is the frequency at which an object naturally vibrates when it is disturbed from its equilibrium or rest position. It is an inherent property of the object and is determined by its mass, stiffness, and the medium through which it vibrates. Natural frequencies are also known as resonant frequencies and are used to …
The source of a sound can be any object that is capable of vibrating and producing sound waves. Examples of sound sources include musical instruments, voices, and machines. Man-made sources of sound Musical instruments Voice Household appliances Transportation vehicles Machinery Alarms Speakers Video game consoles Natural sources of sound Wind Thunder Birds Rain Animals Ocean …
Explain what earthing, charging by contact , charging by induction and principles of capacitors are Earthing : Earthing is the process of connecting an electrical system or component to the ground. This helps to protect the system from electrical shocks, short circuits, lightning strikes and other electrical hazards. Charging By Contact : Charging by contact …

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 …
Protect ourselves when there is a lightning – ഇടിമിന്നൽ ഉണ്ടാകുമ്പോൾ വേണ്ട സംരക്ഷണം Read More »
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 …
