Skill Sheet 20.3 Electrical Power
... In everyday life we hear the word watt mentioned in reference to things like light bulbs and electric bills. The watt is the unit that describes how much power is used when electricity flows. Therefore, the definition of power is the “rate at which energy is flowing.” And since energy is measured in ...

... A magnetically (inductively) coupled inductor circuit consists of more than one coil of inductive wire wound on the same magnetic core. The flux linkage of the z-turn coil is defined as flux Φ times the number of turns z. Each coils has its own flux linkage. The total flux linking each coil is the s ...

... From the expression for power ratios in decibels, we can readily derive the corresponding expressions for voltage or current ratios. Suppose that the voltage V (or current I) appears across (or flows in) a resistor whose resistance is R. The corresponding power dissipated, P, is V2/R (or I2R). We ca ...
