Alternating current power depends on the voltage and the load resistance

Power is the rate of doing work. It is equivalent to an amount of energy consumed per unit time. The same amount of work is done when carrying a load up a ... more

Black-body radiation is the thermal electromagnetic radiation within or surrounding a body in thermodynamic equilibrium with its environment, or emitted by ... more

Every point mass in the universe attracts every other point mass with a force that is directly proportional to the product of their masses and inversely ... more

The electric power produced by an electric current “ I “ passing through an electric potential (voltage) difference of “ V “

The Stefan–Boltzmann law, also known as Stefan’s law, describes the power radiated from a black body in terms of its temperature. Specifically, the ... more

Three phases AC power produced from three sinusoidal voltages which are generated out of phase with each other

Photoelasticity is an experimental method to determine the stress distribution in a material.Unlike the analytical methods of stress determination, ... more

The mechanical output power of the electric motor calculated by the output torque and angular velocity

Mechanical advantage is a measure of the force amplification achieved by using a tool, mechanical device or machine system. Ideally, the device preserves ... more
