WebMar 3, 2024 · The power to which fundamental units are raised in order to obtain the unit of a physical quantity is called the dimensions of that physical quantity. Dimensions of physical quantity do not depend on the system of units. ... S.I. Unit of Power is watt (W). c.g.s. unit of power is erg per second (erg s-1) Dimensions and Unit of Electric Charge ... WebOhm is the electrical unit of resistance. 1Ω = 1V / 1A. Watt (W) Watt is the electrical unit of electric power. It measures the rate of consumed energy. 1W = 1J / 1s. 1W = 1V ⋅ 1A. Decibel-milliwatt (dBm) Decibel-milliwatt or dBm is a unit of electric power, measured with logarithmic scale referenced to 1mW. 10dBm = 10 ⋅ log 10 (10mW / 1mW ... Webjoule, unit of work or energy in the International System of Units (SI); it is equal to the work done by a force of one newton acting through one metre. Named in honour of the English physicist James Prescott Joule, it equals 107 ergs, or approximately 0.7377 foot-pounds. In electrical terms, the joule equals one watt-second—i.e., the energy released in one second … fresh vape pods
