## How do I access Simulink in Matlab?

Open a Model

1. On the MATLAB Toolstrip, on the Home tab, click Simulink.
2. In the Simulink Toolstrip, on the Simulation tab, select Open and click Recent Files to open recent files or Open to search for a model.
3. At the MATLAB Command Window, enter the name of the model without a file extension, for example, vdp .

What is the mathematical model of RLC circuit?

LQ″+RQ′+1CQ=E0cosωt. cosϕ=k−mω2√(k−mω2)2+c2ω2andsinϕ=cω√(k−mω2)2+c2ω2. cosϕ=1/C−Lω2√(1/C−Lω2)2+R2ω2andsinϕ=Rω√(1/C−Lω2)2+R2ω2.

### How do I run Simulink?

1. Start MATLAB®. From the MATLAB toolstrip, click the Simulink button .
2. Click the Blank Model template. The Simulink Editor opens.
3. From the Simulation tab, select Save > Save as. In the File name text box, enter a name for your model. For example, simple_model . Click Save.

To display the Electrical library in the Simulink Library Browser, scroll to the Simscape node. Expand the Simscape node and then the Electrical node. Alternately, at the MATLAB command prompt, enter this command. Thank you for your feedback!

What is difference between Simulink and MATLAB?

The Simulink approach is based on time based and multi rate system. SO that will be useful for HDL code generation. Whereas, MATLAB is for the mathematical based algorithm development and which will not consider the time while in simulation (independent of time). Simulink is graphical and more interactive to the user.

## How do you calculate current in an RLC circuit?

The current Irms can be found using the AC version of Ohm’s law in Equation Irms=Vrms/Z. Irms=VrmsZ=120V531Ω=0.226Aat60.0Hz. Irms=VrmsZ=120V180Ω=0.633Aat10.0Hz. The current at 60.0 Hz is the same (to three digits) as found for the capacitor alone in [link].

## How does RLC circuit work?

This is an RLC circuit, which is an oscillating circuit consisting of a resistor, capacitor, and inductor connected in series. The capacitor is charged initially; the voltage of this charged capacitor causes a current to flow in the inductor to discharge the capacitor.

Why do we use RLC circuit?

RLC circuits are often used as oscillator circuits because they produce sine waves, square waves, or triangle waves. These are oscillating electronic signals that can convert direct current into alternating current or work as a low-pass filter, high-pass filter, band-stop filter, and band-pass filter.
