FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -An electrical network is an interconnection of electrical components (e.g., batteries, resistors, inductors, capacitors, switches, transistors) or a model of such an interconnection, consisting of electrical elements (e.g., voltage sources, current sources, resistances, inductances, capacitances).

Detailed explanation-2: -An electric circuit or electric network is an interconnection of electrical elements linked together in a closed path so that electric current may flow continuously.

Detailed explanation-3: -Every electric circuit, regardless of where it is or how large or small it is, has four basic parts: an energy source (AC or DC), a conductor (wire), an electrical load (device), and at least one controller (switch). Visualize what happens when you switch on a room light.
