Carbon and silicon differ in atomic size and bonding properties. Carbon forms strong covalent bonds due to its smaller size and high electronegativity, enabling versatile organic compounds. Silicon, being larger, forms weaker bonds and primarily engages in extended networks like silicates. For moreRead more

The inductance L of a solenoid depends only on its geometry (number of loops, core material, etc.) and not on the current. Thus, reducing the current to half does not change the inductance of the solenoid. For more visit here: https://www.tiwariacademy.com/ncert-solutions/class-12/physics/chapter-8/

Alloys are preferred for standard resistors because they have high resistivity and low temperature coefficients of resistance. This ensures minimal variation in resistance with temperature changes, providing stability and accuracy. Alloys like manganin and constantan are commonly used for their duraRead more

In a p-n junction at equilibrium, diffusion of charge carriers (electrons and holes) is balanced by drift due to the built-in electric field of the depletion region. These opposing currents cancel each other out, resulting in no net current flow across the junction under equilibrium conditions. ForRead more

A solenoid with N loops of wire tightly wrapped around an iron core is carrying an electric current. If the current through this solenoid is reduced to half, then what change would you expect in inductance L of solenoid?
The inductance L of a solenoid depends only on its geometry (number of loops, core material, etc.) and not on the current. Thus, reducing the current to half does not change the inductance of the solenoid. For more visit here: https://www.tiwariacademy.com/ncert-solutions/class-12/physics/chapter-8/

In a p-n junction, under equilibrium, there is no net current. Why?
In a p-n junction at equilibrium, diffusion of charge carriers (electrons and holes) is balanced by drift due to the built-in electric field of the depletion region. These opposing currents cancel each other out, resulting in no net current flow across the junction under equilibrium conditions. ForRead more
