Current Formula 3 (Power and Resistance, Ohmic Loss, Resistive Heating) We know that, Now substituting Ohm’s law into the above equation we get, Thus, the current is the square root of the ratio of power and resistance. Mathematically, the formula for this is equal to: Example As shown...
Volt can be defined as the electric potential difference between two points in an electric circuit that dissipates one joule of energy per coulomb of charge that passes through the electric circuit. Mathematically, it can be expressed as,Hence...
measured in units of energy or work—e.g.,microjoules (10-6joule) per second per square centimetre—or in units of power, as microwatts (10-6watt) per square centimetre. Unlikeloudness, sound intensity is objective and can be measured by auditory equipment independent of an observer’s ...
The wavelength of the emitted radiation is inversely proportional to its frequency, or λ =c/ν. The value of Planck’s constant is defined as 6.62607015 × 10−34joule∙second. Britannica Quiz Physics and Natural Law For a blackbody at temperatures up to several hundred degrees, the majori...
