Can I model multiple capacitors in series or parallel?
Use the calculated value and combine using 1/C_total = Σ(1/C) for series or sum them directly for parallel arrangements.

Capacitance Calculator Guide
Use this companion guide beside the interactive calculator to make sure you understand the “why” behind every click. Each section includes the classroom explanation, student-friendly language, and quick practice prompts.
Before you start
Collect the data points listed below and double-check their units. Keeping an organized “givens” list is one of the fastest ways to reduce math errors and impress exam graders.
- capacitance
- farads
- dielectric
Detailed procedure
Step 1
Enter plate area and separation distance (the calculator converts centimeters or millimeters to meters).
Step 2
Select the dielectric material or provide a custom relative permittivity.
Step 3
Review capacitance in farads with microfarad and picofarad conversions.
Teaching & troubleshooting tips
Does fringe capacitance affect the result?
This formula assumes large, parallel plates. Edge effects are ignored, which is acceptable for quick estimates.
