An RL circuit, also known as an RL filter, resistor-inductor circuit, or RL network, is a circuit that can be constructed using passive circuit components such as resistors and inductors and connected to a current or voltage source. In other words, XL = XC. 3.RL.2.5 Refer to parts of stories, dramas, and poems when writing or speaking about a text . A series RL circuit is a circuit that contains a pure inductance of L (Henry) connected to a pure resistance of R ohms in series. A band-pass filter can be formed with an RLC circuit by either placing a series LC circuit in series with the load resistor or else by placing a parallel LC circuit in parallel with the load resistor. 1. Antoniu Miclaus [antoniu.miclaus@analog.com] is a system applications engineer at Analog Devices, where he works on ADI academic programs, as well as embedded software . Once the current reaches this maximum steady state value at 5τ, the inductance of the coil has reduced to zero . The switch, S, is closed at t = 0. The sudden application of current or voltage to the circuit containing a resistor, inductor, and switch leads to the response of a circuit, which is called the transient response of the RL circuit.

A first order RL circuit is one of the simplest analog infinite impulse response electronic filters. The total impedance of a RL circuit is given by the formula: Z is the total opposition offered to the flow of current in the circuit. Remember that for an RL circuit the current I lags the source voltage Vin. RL circuit is also employed in RF equipment. The zero-input response (ZIR), also called the natural response, of an RL circuit describes the behavior of the circuit after it has reached constant voltages and currents and is disconnected from any power source. It is also called a resonant circuit, tank circuit, or tuned circuit. The Norton current is equal to the short circuit current. When we apply an ac voltage to a series RL circuit as shown below, the circuit behaves in some ways the same as the series RC circuit, and in some ways as a sort of mirror image. and the bandwidth for the series circuit is. Figure 2. Find (a) the equation for i (you may use the formula rather than DE), (b) the current at t = 0.5 s (c) the expressions for VR and VL (d) the time at which VR = VL Answer Two-mesh Circuits An RLC circuit is an electrical circuit it consists of a resistor, inductor, and capacitor they are represented by the letters R, L and C. The resonant RLC circuits are connected in series and parallel. There are several ways to locate a circuit fault. At t = 0, a sinusoidal voltage V cos (ωt + θ) is applied to the series R-L circuit, where V is the amplitude of the wave and θ is the phase angle. In a series RLC circuit there becomes a frequency point were the inductive reactance of the inductor becomes equal in value to the capacitive reactance of the capacitor. Applications of RLC Circuits RLC Circuits are used world wide for different purposes. Note that the circuit connected to the inductor before t = t 0 is a Norton equivalent, and the circuit connected to the capacitor is a Thevenin equivalent. What is the application of RLC Circuit?
