Circuit Loads:
A load generally refers to a component or a piece of equipment connected to the output of an electriccircuit. In its fundamental form, the load is represented by any one or a combination of the following:
1.Resistor(R)
2.Inductor(L)
3.Capacitor(C)
A load can either be of resistive, inductive or capacitive nature or a blend of them. For example,a light bulb is a purely resistive load where as a transformer is both inductive and resistive. A circuit load can also be referred to as a sink since it dissipates energy whereas the voltage or current supply can be termed as a source.
Table shows the basic circuit elements along with their symbols and schematics used in an electric circuit.The R,L and C are all passive components i.e. they do not generate their own emf whereas the DC voltage and current sources are active elements.
