Electrical Analogy for Thermal Conduction

Electrical Analogy for Thermal Conduction Thermal Conductivity is defined as the quantity of heat (Q) transmitted through a unit thickness (l) in a direction normal to a surface of unit area due to a unit temperature gradient (ΔT) under steady state condition and when the heat transfer is dependent only on the temperature gradient.

Basic Properties of Electric Charge

Basic Properties of Electric Charge Electric charge is defined as the amount of energy or electrons passing from one body to another either by conduction, induction or other specific methods. There are two types of electric charges namely Positive Charge and Negative Charges.  Charges are present in almost everybody and those bodies which don’t have Read more about Basic Properties of Electric Charge[…]

Variation of Acceleration due to gravity due to Altitude

Variation of Acceleration due to gravity due to Altitude Gravity is the force of attraction exerted by earth towards its centre on a body lying on or near the surface of earth. Gravity is merely a special case of gravitation and is also called earth’s gravitational pull. The force of attraction between two bodies on Read more about Variation of Acceleration due to gravity due to Altitude[…]
