1

Create the basic Simscape Power Systems model

Open Simulink and create a new model. Add a AC Voltage Source block and a Series RLC Branch block from the Simscape > Electrical > Specialized Power Systems library. Connect the voltage source to the resistor in series.

Simulink

% Add AC Voltage Source and Series RLC Branch blocks and connect them in series
% Your code here

Hint

Use add_block to add components and add_line to connect them.

2

Configure the voltage source and resistor values

Set the Amplitude parameter of the AC Voltage Source block to 230. Set the Branch type of the Series RLC Branch block to R and its Resistance (Ohms) parameter to 10.

Simulink

% Set AC Voltage Source amplitude to 230
% Set Series RLC Branch to resistor with 10 ohms
% Your code here

Hint

Use set_param to set block parameters.

3

Configure simulation parameters

Set the simulation stop time to 0.1 seconds using the set_param function on the model.

% Set simulation stop time to 0.1 seconds
% Your code here

Hint

Use set_param on the model name to set the stop time.

4

Run the simulation and display results

Run the simulation using sim(model). Then, use the Simscape logging feature to plot the voltage across the resistor and the current through it.
