name: rlc-circuit-drawing-generator description: Generates RLC circuit diagrams from text descriptions using Schemdraw. Use this skill when the user wants to create circuit drawings for educational purposes, particularly for AC/DC circuits with resistors, capacitors, inductors, and power sources.

RLC Circuit Drawing Generator

This skill generates professional circuit diagrams from natural language descriptions using Python's Schemdraw library.

When to Use This Skill

• User asks to draw or create a circuit diagram
• User describes a circuit with resistors, capacitors, inductors, or power sources
• User needs an educational circuit illustration
• User wants to visualize an RLC circuit topology

Workflow

1. Parse the circuit description - Identify components, values, and topology
2. Determine layout - Series, parallel, or mixed arrangement
3. Generate Schemdraw code - Create Python script using library conventions
4. Render to image - Execute script to produce SVG output

Input Format

Users can describe circuits in natural language:

• "Draw a series RLC circuit with R=100Ω, L=10mH, C=1μF powered by 12V DC"
• "Create an RC low-pass filter with a 10kΩ resistor and 100nF capacitor"
• "Show a parallel LC circuit with L=1mH and C=100pF"

Layout Convention

Preferred layout: Vertical component arrangement on the right side.

    ┌───────────────────┐
    │                   │
   (+)                [R₁]
  (SRC)                 │
   (-)                [L₁]
    │                   │
    └────────⏚────────[C₁]
           (GND)        │
                        │

• Power source: Vertical on left side, positive terminal on top
• Components: Arranged vertically on the right side using .down()
• Ground: Reference point on the return path (bottom)
• Labels: Include component designators and values (R₁ 10kΩ) - use default positioning

Schemdraw Code Generation

Use the bundled references for syntax:

• references/schemdraw-guide.md - Component elements and methods
• references/circuit-patterns.md - Common topology templates

Basic Structure (Vertical Layout - Preferred)

Important: The ground must be connected to the source negative terminal to form a complete circuit.

Labeling: Use .label('text') without specifying loc - Schemdraw's default positioning handles placement intelligently based on element orientation.

import schemdraw
import schemdraw.elements as elm

with schemdraw.Drawing() as d:
    d.config(unit=3, fontsize=12)

    # Start with power source (vertical, positive up)
    source = d.add(elm.SourceV().up().label('V₁\n12V'))

    # Top rail to the right
    d += elm.Line().right().length(5).at(source.end)

    # Components arranged vertically using .down()
    d += elm.Resistor().down().label('R₁  100Ω')
    d += elm.Inductor().down().label('L₁  10mH')
    d += elm.Capacitor().down().label('C₁  1μF')

    # Return path with ground
    d += elm.Line().left().length(3)
    d += elm.Ground()

    # Connect back to source negative terminal
    d += elm.Line().left().tox(source.start)
    d += elm.Line().up().toy(source.start)

    d.save('circuit.svg')

Rendering

After generating the Schemdraw code, save it to a .py file and render:

python scripts/render_circuit.py circuit_code.py output.svg

Or run the generated Python directly if Schemdraw is installed.

Components Reference

Output

• Default format: SVG (scalable, web-friendly)
• Alternatives: PNG, PDF (specify in render command)
• Location: Same directory as the Schemdraw script, or user-specified path
