## Component Models

This directory contains EMT component model notes for devices connected to EMT
buses.

A component README should include:
1. Model parameters and derived parameters
2. Internal and external variables
3. Differential and algebraic equations
4. Bus residual contributions, when applicable
5. Initialization notes
6. Monitorable outputs

### Types

- `BranchLumpedConstant` (See [BranchLumpedConstant](branch/branch-lumped-constant/index.md))
- `LoadRL` (See [LoadRL](load-rl/index.md))
- `VoltageSource` (See [VoltageSource](voltage-source/index.md))
