6 days ago · Power is the rate at which energy is transferred, used or transformed. The unit of power is a joule per second (J/s), which is also known as a watt. The more wattage the more power or electrical energy is used per unit time. For example, the rate at which a light bulb transforms electrical energy into heat and light is measured in watts.
4 days ago · In mathematics, exponentiation is an operation involving two numbers: the base and the exponent or power. Exponentiation is written as b n, where b is the base and n is the power; this is pronounced as "b (raised) to the (power of) n ".
3 days ago · heat, energy that is transferred from one body to another as the result of a difference in temperature. If two bodies at different temperatures are brought together, energy is transferred—i.e., heat flows—from the hotter body to the colder.

3 days ago · The single most important characteristic of an atom is its atomic number (usually denoted by the letter Z ), which is defined as the number of units of positive charge (protons) in the nucleus. For example, if an atom has a Z of 6, it is carbon, while a Z of 92 corresponds to uranium.
6 days ago · Wind power is a form of energy conversion in which turbines convert the kinetic energy of wind into mechanical or electrical energy that can be used for power. Wind power is considered a form of renewable energy.
5 days ago · (a) Let’s define power first, Power is the rate at which a work is done or power is the amount of energy transferred or converted per unit time. As per definition, we can define power as, \[P=\dfrac{W}{T}=\dfrac{E}{T}\]
