Parallel Circuit
Parallel circuits are those circuits which have two or more components connected across the same voltage source (Figure 17). Resistors R 1 ,R2, and R3 are in parallel with each…
Series Circuit
A series circuit is a circuit where there is only one path for current flow. In a series circuit (Figure 16), the current will be the same throughout the circuit.…
Electric Circuit : Open & Short Circuits
Each electrical circuit has at least four basic parts: a source of electromotive force, conductors, load or loads, and some means of control. In Figure 13, the source of EMF…
Resistivity
Resistivity is defined as the measure of the resistance a material imposes on current flow. The resistance of a given length of conductor depends upon the resistivity of that material,…
Wiring Diagram
 A wiring diagram is a very simple way to show wiring connections in an easy-to-follow manner. These types of diagrams are normally found with home appliances and automobile electrical systems…
Block Diagram
A block diagram is used to show the relationship between component groups, or stages in a circuit. In block form, it shows the path through a circuit from input to…
Single Line Diagram
The one-line, or single-line, diagram shows the components of a circuit by means of single lines and the appropriate graphic symbols. One-line diagrams show two or more conductors that are…
Schematic Diagram
Schematic diagrams are the standard means by which we communicate information in electrical and electronics circuits. On schematic diagrams, the component parts are represented by graphic symbols. Because graphic symbols…
Full-Wave Rectifier Circuit
A full-wave rectifier circuit is a circuit that rectifies the entire cycle of the AC sine-wave. A basic full-wave rectifier uses two diodes. The action of these diodes during each…
Half-Wave Rectifier Circuit
When a diode is connected to a source of alternating voltage, it will be alternately forward-biased, and then reverse-biased, during each cycle of the AC sine-wave. When a single diode…
