Capacitor Calculator

This utility app calculates the time constant and energy stored in a capacitor. It helps understand the time-delay characteristics of electrical circuits when a voltage is applied.

Highlights
  • Calculate time constant (RC)
  • Calculate energy stored (E)
  • Input voltage, capacitance, and resistance
  • Understand capacitor charging/discharging
  • Analyze circuit time-delay

Capacitor Calculator is an all-in-one toolkit for students, hobbyists, technicians, and electrical engineers who work with capacitors every day. Whether you are designing an RC circuit, sizing a power supply, building a flash circuit, or studying electromagnetism for an exam, this app gives you fast and accurate answers together with the formulas and calculation steps behind every result. THREE CALCULATORS IN ONE APP 1. Capacitor Charge and Time Constant Enter supply voltage (V), capacitance (C), and series resistance (R) to instantly calculate: • Stored energy: E = 0.5 * C * V^2 • RC time constant: T = R * C • Charge stored: Q = C * V 2. Parallel Plate Capacitance Compute capacitance using plate area, separation distance, and relative permittivity with: C = e0 * er * A / d Perfect for understanding how geometry and dielectric materials affect capacitance. 3. Spherical Capacitor Calculate capacitance between two concentric conducting spheres using: C = 4 * pi * e0 * er * R1 * R2 / (R2 - R1) Choose from built-in dielectric materials including vacuum, air, paper, glass, mica, ceramic, polyethylene, polystyrene, Teflon, silicon, and water. BUILT FOR REAL WORK • Unit-aware inputs for voltage, capacitance, resistance, length, and area • Scientific notation for very small or very large values • Full calculation steps with formulas and substituted values • Copy results with one tap • Save and review calculation history • Everything runs on-device with no tracking, no account, and no internet required A POLISHED NATIVE IOS EXPERIENCE • Full Light Mode and Dark Mode support • Reference tab with physical constants, formulas, and dielectric materials table Capacitor Calculator is a focused tool for electrical engineering, electronics design, physics homework, and EE coursework.
