📖 Capacitance Conversion Guide
🎯 What is Capacitance?
Capacitance is the ability to store electrical charge. It's measured in farads (F) and relates charge (Q) to voltage (V): C = Q/V.
  • Farad (F) is the base unit
  • Most practical values are in μF, nF, pF
  • Higher capacitance = more charge storage
  • Voltage rating is critical for safety
🔧 Unit Prefixes
Understanding metric prefixes is essential for working with capacitance values in electronics.
  • pico (p) = 10⁻¹² (0.000000000001)
  • nano (n) = 10⁻⁹ (0.000000001)
  • micro (μ) = 10⁻⁶ (0.000001)
  • milli (m) = 10⁻³ (0.001)
⚡ Capacitor Behavior
Understanding how capacitors behave in circuits is fundamental to electronics design.
  • Blocks DC, passes AC current
  • Charging follows exponential curve
  • Time constant τ = RC
  • Energy storage E = ½CV²
🚀 Selection Guidelines
Choosing the right capacitor requires considering multiple factors beyond just capacitance value.
  • Voltage rating > maximum circuit voltage
  • Consider temperature coefficient
  • Account for tolerance requirements
  • ESR important for high-frequency
🔬 Common Applications
Capacitors serve many functions in electronic circuits and systems.
  • Power supply filtering and smoothing
  • AC coupling and DC blocking
  • Timing circuits and oscillators
  • Energy storage and backup power
📏 Measurement Tips
Accurate capacitance measurement requires proper techniques and understanding of limitations.
  • Discharge capacitors before measuring
  • Use appropriate test frequency
  • Consider parasitic effects
  • Account for temperature effects
