In the 3rd century BC, the ancient Greek scientist Archimedes discovered that if the distance between the two objects on the lever and the fulcrum is inversely proportional to their weight, the lever is balanced. Later people summarized it as "the lever principle." In layman's terms, the lever principle is: Resistance × resistance arm = power × power arm (Figure 26.2-1).

Knowledge Points Inverse Proportional Functions in Physical Electricity

The output power P (watts) of the electrical appliance, the voltage U (volts) at both ends and the resistance R (ohms) of the electrical appliance have the following relationship: PR = U2. This relationship can also be written as P=______, or R=_____
