RLC Impedance & Phase Angle Calculator
Compute complex impedance, magnitude |Z| and phase angle φ for series or parallel RLC circuits: X_L=2πfL, X_C=1/(2πfC), |Z|=√(R²+X²), φ=atan2(X,R). Supports any subset of R/L/C and an optional linear frequency sweep.

MCP integration
Add this tool to your Model Context Protocol server so AI agents can list and call it.

}List available tools
After connecting to the SSE endpoint, list the exposed tools:
tools/list
{
"jsonrpc": "2.0",
"id": 1,
"method": "tools/list"
}Call this tool
Invoke the tool by its id, passing arguments built from its parameters:
tools/call
{
"jsonrpc": "2.0",
"id": 2,
"method": "tools/call",
"params": {
"name": "impedance-calculator",
"arguments": {
"topology": "series",
"R": 100,
"L": 0.1,
"C": 0.00001,
"frequency": 50,
"sweepEnable": false,
"sweepStart": 0,
"sweepEnd": 0,
"sweepPoints": 10,
"decimalPlaces": 4
}
}
}Chain multiple tools in one session with a comma-separated toolId list, e.g. /mcp/sse?toolId=png-to-webp,jpg-to-webp,gif-to-webp (max 20).
