Capacitive Timing Analysis
- Enter the Resistance (Ω) of the circuit path.
- Input the Capacitance (μF) of the component.
- Enter the Source Voltage (V) being applied.
- Set the Observed Time (s) to see the state at that point.
- View the Interactive RC Curve to visualize the charge vs. time.
- Check the Time Constant (τ) and Energy (Joules) results.
Frequently Asked Questions
What is the RC Time Constant (τ)?
The time constant (τ) is equal to Resistance (R) multiplied by Capacitance (C). It is the time required for the capacitor to charge to 63.2% of its maximum voltage.
How long until a capacitor is fully charged?
Theoretically, it never stops charging. In practice, a capacitor is considered 'fully charged' (over 99.3%) after 5 time constants (5τ).
What is the energy unit 'Joules'?
Joules (J) measure the amount of electrical energy stored in the capacitor's electric field. Energy = 0.5 × C × V².
Why use μF instead of F?
The Farad (F) is an extremely large unit of capacitance. Most consumer capacitors range from picofarads (pF) up to millifarads (mF), so microfarads (μF) is the most common industry unit.
