- **分类:** Physics

## 概述

Interactive visualization of electric power formulas and practical applications. Explore the fundamental power formulas P = V×I = I²R = V²/R with real-time circuit visualization showing voltage source, resistor, current flow with animated direction indicators, and dynamic power display. Features three synchronized formula displays showing calculations using different known quantities, interactive controls for voltage (1-500V), current (0.1-20A), and resistance (1-1000Ω), device presets for common appliances (LED 10W, air conditioner 1500W, rice cooker 800W, fan 115W), energy and cost calculator with adjustable usage time (0.1-24h) and electricity price, Joule heating visualization with temperature-based color gradients showing Q = I²Rt heat generation, and comprehensive educational content covering electric power fundamentals, formula relationships using Ohm's law, energy vs power concepts, practical applications in household appliances, and electrical safety. Real-time calculations display voltage, current, resistance, power, energy consumed (kWh and joules), estimated cost, and heating effects. Circuit animation shows current direction with speed proportional to current magnitude. Multi-language support (zh, en, fr, de, es, pt, ru).
