The spring force is also called the restoring force. The spring force is negative because the direction of the force exerted by spring is... View Article
Silver is a dielectric material. Dielectric materials get polarised in an electric field. They are used to increase the capacitance of the capacitor.... View Article
Dielectric properties of the plastic depend on their structure. Depending on the structure they are called polar or nonpolar. Polar plastics... View Article
An ideal inductor and ideal capacitor will not consume any power because the internal resistance will be zero. If the inductor and capacitor are... View Article
In amplitude modulation, the amplitude of the carrier signal is changed in proportion to the message signal. The modulation index is given by the... View Article
AND gate and NAND gate can be made by connecting transistors, diodes and resistors. AND gate can be converted into a NAND gate by adding a NOT circuit... View Article
The acceleration depends on the force. The acceleration of an object is directly proportional to the force applied to the object and inversely... View Article
Schrodinger proposed the quantum model of the atom. In the quantum model, the electrons are treated as matter waves. According to the uncertainty... View Article
When voltage is applied across the capacitor, electrons are pulled away from one plate and the electrons are accumulated on the other plate. Even... View Article
Yes, a single charge creates an electric field in the free space around the charge. The electric field points away from the single positive... View Article
Acceleration does not increase in a free fall. The acceleration on the surface of the earth is approximately equal to 9.8 m/s2. The velocity... View Article
The space between the molecules increases when water is heated. A particular volume of hot water will have lesser molecules than the same volume... View Article
Pauli’s exclusion principle is not a force. It is a quantum mechanical principle that states that more than one fermions cannot occupy the same... View Article
Pendulum stops swinging eventually because the amplitude of the pendulum reduces due to damping. Damping is when the frictional force between air... View Article
If the source of light and the screen are at a finite distance from the obstacle causing the diffraction then it is Fresnel diffraction. If there... View Article
