Current Division Formula:
From: | To: |
Current division in two capacitors refers to how current distributes between two capacitors connected in parallel in an electrical circuit. The current through each capacitor is proportional to its capacitance value when a current source is applied.
The calculator uses the current division formula:
Where:
Explanation: The formula shows that current divides between capacitors in proportion to their capacitance values, with larger capacitors carrying more current.
Details: Understanding current division in capacitive circuits is essential for circuit analysis, filter design, and ensuring proper current distribution in parallel capacitor configurations.
Tips: Enter source current in amperes, both capacitance values in farads. All values must be positive numbers greater than zero.
Q1: Does this formula work for capacitors in series?
A: No, this specific formula applies to capacitors connected in parallel with a current source.
Q2: What happens if the capacitance values are equal?
A: If C1 = C2, the current will divide equally between the two capacitors.
Q3: Can this calculator be used for AC circuits?
A: This calculation is for DC steady-state conditions. For AC circuits, impedance calculations would be needed.
Q4: What are typical capacitance values used in circuits?
A: Capacitance values typically range from picofarads (pF) to microfarads (μF), though larger values are used in power applications.
Q5: How does voltage affect current division in capacitors?
A: In parallel capacitors, voltage is the same across both, so current division depends solely on capacitance values for a given source current.
