Capacitor Calculator
Calculate capacitor values, charge, energy storage, and time constants. Perfect for electronics projects, circuit design, and educational purposes.
Step 1: Basic Parameters
100 μF
12 V
Understanding Capacitance
Capacitance is measured in Farads (F). Common values range from pF (picofarads) to μF (microfarads) for regular capacitors, and up to F (Farads) for supercapacitors.
Step 2: Circuit Configuration
About Circuit Configurations
Series capacitors have reduced total capacitance. Parallel capacitors have increased total capacitance. RC circuits combine resistors and capacitors for timing applications.

Key Formulas
Energy (J) = ½ × C × V² | Charge (Q) = C × V | Time Constant (τ) = R × C
Energy stored in a capacitor: E = ½CV². Charge stored: Q = CV. Time constant for RC circuit: τ = RC.
