An example of purely resistive would be heaters or heating rods in an industrial oven. (Capacitance and inductance so low that it has no effect of the impedance of the system)
An example of a capacitive load would be a DC power supply (obiously, it uses large caps to smooth as well as maintain DC power). A battery would also have a larger capacitance than either inductance or resistance. If a battery had a high resistance, it would deplete very quickly...not to mention get very hot (as it does when you short it out..but that's because of high current! )
Inductive would include AC motors in many types of machinery.
All of these items have a component of everything...but for all practical purposes, several components are essentially zero for calculations.
There may be corrections to my above information....it's so easy to forget some of this stuff!
