Basic Network Theorem

What do you mean by a linear circuit element?

Circuit elements are linear when they follow Ohm’s law so that doubling the voltage across them doubles the current through them.

What do you mean by bilateral circuit elements?

Circuit elements are bilateral if current can pass through them in either direction with equal simplicity.

What are the applications of current sources?

1.       They are used to represent certain devices that exhibit a constant current behavior. Transistors are examples of such devices.
2.       Current sources can also be used to represent equipment such as current regulated power supplies. These supplies provide a constant current over some limited range of load resistance.
3.        They can be used in certain network analysis procedures.
