Planar and Non Planar Graphs of Circuit

Graph theory plays very crucial role in understanding of complicated electrical circuits. Now what that actually means is a circuit consisting of more than six loops are very complicated to handle manually with pen and paper. If we have computer with multisim then it becomes a easy to handle task but without computer task become too complicated so to simply analysis of such circuit we often prefer Graph Theory. How are Graphs...

Resonance in Series RLC Circuit

Consider a RLC circuit in which resistor, inductor and capacitor are connected in series across a voltage supply. This series RLC circuit has a distinguishing property of resonating at a specific frequency called resonant frequency. In this circuit containing inductor and capacitor, the energy is stored in two different ways. When a current flows in an inductor, energy gets stored in magnetic field. When a capacitor is charged, energy...

Resistances in Series and Resistances in Parallel

More than one electrical resistance can be connected either in series or in parallel in addition to that, more than two resistances can also be connected in combination of series and parallel both. Here we will discuss mainly about series and parallel combination. Resistances in Series Suppose you have, three resistors, R1, R2 and R3 and you connect them end to end as shown in the figure below, then it would be referred as resistances...

Parallel RLC Circuit

Consider a RLC circuit in which resistor, inductor and capacitor are connected in parallel to each other. This parallel combination is supplied by voltage supply, VS. This parallel RLC circuit is exactly opposite to series RLC circuit. In series RLC circuit, the current flowing through all the three components i.e the resistor, inductor and capacitor remains the same, but in parallel circuit, the voltage across each element remains the...

Series RLC Circuit

When resistor, inductor and capacitor are connected in series across a voltage supply, the circuit so obtained is called series RLC circuit. Phasor Diagram of Series RLC Circuit The phasor diagram of series RLC circuit is drawn by combining the phasor diagram of resistor, inductor and capacitor. Before doing so, one should understand the relationship between voltage and current in case of resistor, capacitor and inductor. Resistor In...

Construction and Working of AC Circuits

Bridge circuit is nothing but the electrical circuit configuration which is used to measure unknown values of the resistance, impedance, induction, and capacitance. Many bridges like Wheatstone bridge, Maxwell Bridge, Kelvin Bridge, and many more are very useful to measure quantities with accuracy and working on the same principle. Here is a brief description of functioning of some of the bridges given below: Wheatstone Bridge A...
