Capacitor Calculator vs Vector Calculator Plus
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
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.
- 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.

Vector Calculator is math calculator to find vector addition fast and easy. Vector Calculator give operation of adding two or more vectors together into a vector sum. The parallelogram law gives the rule for vector addition of two or more vectors. Features: • Instant vector calculation. • Add multiple vector by x, y, magnitude or angle. • Vector Image is generated upon calculation. • Save Vector Image into camera roll. • Option to show/hide Grid, Indicator, Label, Vector Label or Magnitude Label for Vector Graph. • Option to enable/disable Background for Vector Graph. • Option to set Background Colour for Vector Graph. A Vector has magnitude [size] and direction. No matter which order you add them, you will get the same result. Magnitude of a Vector: The magnitude of a vector is shown by two vertical bars on either side of the vector |a| Adding Vectors: Vectors can add by adding the x parts and adding the y parts: Example: add the vectors a = (2,3) and b = (4,5) |a+b| = |a| + |b| |a+b| = (2,3) + (4,5) = (2+4,3+5) = (6,8) Common examples of vectors are force and velocity. Both force and velocity are in a particular direction. The magnitude of the vector would indicate the strength of the force or the speed associated with the velocity. Vector Calculator is useful for math teachers, educator, or anyone who want to prepare vector math material for teaching. Also for students who need to learn more detail or understanding of math vector addition operation. Thanks for your support and do visit nitrio.com for more apps for your iOS devices.
