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 same and the current gets divided in each component depending

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 acurrentflows in an inductor, energy gets stored inmagnetic field. When a capacitor is charged, energy gets stored in static electric field.The magnetic field in the in

What is a Series RLC Circuit?A series RLC circuit is one the resistor, inductor and capacitor are connected in series across a voltage supply. The resulting circuit is called series RLC circuit. A circuit and phasor diagram for a series RLS circuit has been shown below.Phasor Diagram of Series RLC CircuitThe 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

In an RLC circuit, the most fundamental elements of a resistor, inductor, and capacitor are connected across a voltage supply. All of these elements are linear and passive in nature. Passive components are ones that consume energy rather than producing it; linear elements are those which have a linear relationship between voltage and current.There are number of ways of connecting these elements across voltage supply, but the most common method is to connect these elements either in series or in

What is the Time Constant?The time constant – usually denoted by the Greek letter τ (tau) – is used in physics and engineering to characterize the response to a step input of a first-order, linear time-invariant (LTI) control system. The time constant is the main characteristic unit of a first-order LTI system.The time constant is commonly used to characterize the response of an RLC circuit.To do this, let us derive the time constant for an RC circuit, and the time constant for an RL circuit.Tim

What is an RC Circuit?An RC circuit (also known as an RC filter or RC network) stands for a resistor-capacitor circuit. An RC circuit is defined as an electrical circuit composed of the passive circuit components of a resistor (R) and capacitor (C), driven by a voltage source or current source.Due to the presence of a resistor in the ideal form of the circuit, an RC circuit will consume energy, akin to an RL circuit or RLC circuit.This is unlike the ideal form of an LC circuit, which will consum

What is an LC Circuit?An LC circuit (also known as an LC filter or LC network) is defined as an electrical circuit consisting of the passive circuit elements an inductor (L) and a capacitor (C) connected together. It is also called a resonant circuit, tank circuit, or tuned circuit. An LC – Circuit Due to the absence of a resistor in the ideal form of the circuit, an LC circuit consumes no energy. This is unlike the ideal forms of RC circuits, RL circuits, or RLC circuits, which consume ene
