The flowing liquid metal in the outer core of the planet generates electric current. The rotation of Earth on its axis results in these electric... View Article
When the magnet is moved away from the coil, the galvanometer shows deflection in the opposite direction indicating that the direction of the... View Article
Coulomb’s law signifies the inverse square dependence of electric force. The law is also used in the derivations of Gauss' law for general cases... View Article
Each charge will have its own electric field and both these fields influence each other. The net electric field between them will be the... View Article
To know if the given spring obeys Hooke’s law or not, record each stretching force in Newtons and the corresponding length of the spring. The... View Article
When a wave propagates through a medium, the particles of the medium start vibrating and this vibration is known as oscillation. If this... View Article
Materials such as silicon (Si), germanium (Ge) and gallium arsenide (GaAs) whose electrical properties lie somewhere between that of an conductor... View Article
Direct current deposits anions in the anode and cations in the cathode. Incase of an alternating current, the current would keep changing... View Article
A higher voltage applied to the cell indicates that the cathode will have more energy to carry out reduction similarly, the anode will have more... View Article
The modulus of elasticity or Young’s modulus is the measure of the stiffness fof an object. Diamond has a high modulus of elasticity. A high... View Article
The direction of the moment depends upon the axis of rotation with respect to which you are measuring the turning effect. Clockwise and... View Article
Momentum is a vector quanitity which has both magnitude and direction. Because momentum has direction, it can be used to predict the direction... View Article
Electric Charge is the property of subatomic particles that causes it to experience a force when placed in an electromagnetic field. There are... View Article
Although electrostatically induced forces seem rather weak, some electrostatic forces such as the one between a proton and an electron is about... View Article
When the amplitude of the sound waves is increased, the sound wave is perceived to be louder; likewise, if the amplitude of the sound wave... View Article
A charged particle exerts a force on particles around it. The area of the influence of this force is known as the electric field. An electric... View Article
