A fuse wire is used in an electric circuit to prevent excess current from flowing in the circuit. By melting and breaking the circuit when the current exceeds a safe level, the fuse protects the electrical components and wiring from ...
The unit of resistance is the ohm (symbol: Ω). Resistance is a measure of how much a material or device opposes the flow of electric current. It quantifies the degree to which a conductor resists the passage of electrons. The ...
Alternating current (AC) is converted into direct current (DC) using a rectifier. A rectifier is an electrical device that converts AC, which periodically changes direction, into pulsating DC by allowing current to flow in only one direction. This process involves ...
The work done in moving a unit positive charge from one point to another in an electric circuit is measured by the potential difference between those points. This quantity represents the energy required to move the charge and is a ...
Light travels slower in glass than in air because the refractive index of air is less than the refractive index of glass. The higher refractive index of glass indicates that light interacts more with the glass material, causing it to ...
Lambert’s law relates to the absorption of light by a material. It describes how the intensity of light absorbed by a material is directly proportional to the thickness of the material and the concentration of the absorbing substance.
A cylindrical lens is used to correct the defect of astigmatism. This lens has different curvatures in different meridians, allowing it to compensate for the uneven curvature of the cornea or lens of the eye, thereby improving vision for astigmatic ...
The reason for the elliptical appearance of the Sun and the Moon near the horizon is refraction. When these celestial bodies are close to the horizon, their light passes through a thicker layer of the Earth’s atmosphere, causing their image ...
When light waves pass from air to glass, only the wavelength and velocity are affected. The frequency remains constant as it depends on the source. The wavelength decreases in glass due to its higher refractive index, while the velocity decreases ...
