The gravitationalforce on 1 L of water is 9. I f the motor operates at an efficiency of 90 percent and the generator at an schaun of 80 percent, and if the input power to the motor is 5 kW, find the output power from the generator.
This speeding up and sloiving doiz n occurs continually as free electrons move among conductor atoms. The SI u n i t of resistance is the o h hith symbol R, the Greek uppercase letter omega. The quantity symbol is R.
In metallic and some other types of conductors, the current is proportional to the applied voltage: Doubling the voltage doubles the current, tripling the voltage triples the current. Also, the electric resistance of a conductor is 1 R if an applied koltage of 1 V causes a current of 1 A to flow.

The inverse of resistance is often useful. The SI unit of conductance is the sicwicrzs u. Since conductance is the incerse of resistance.
Resistance is also a function of the temperature of the conductor, a s is explained in the next section. At a fixed temperature the resistance of a conductor is where 1 is the conductor length in meters and A is the cross-sectional area in square meters. Table sholvs colwo resistivities of some materials at 20 C.

A good conductor has a resistivity close to 10 R. Silver, the best conductor.
Copper is a common conductor, a s is aluminum. They can provide physical support without significant current leakage. Materials with resistivities in the range of to Q.
