Simple supercapacitor fast charging circuit
I have some 2.7 V, 500 F supercapacitors and I would like to quickly charge them from two 18650 VTC6s in parallel. I made this simple circuit and I would like to make sure it works before I

Calculate the capacitance of a supercapacitor
Is the formula for capacitance of a supercapacitor C = epsilon(A/d) ? Since a supercapacitor does not have a dielectric, then will the permitivity be the permitivity of free space ?
capacitor
For the purpose of a project I wish to power an arduino using a supercapacitor charged to 5V. The supercapacitor will be fed straight into the power Vin and GND terminals on the Arduino. No
supercapacitor
What''s the formula to calculate how many seconds a supercapacitor can provide power when employing a buck/boost converter? Also, how different would that calculation be when using a pair of superc...
Low Charging Current Requirement for Supercapacitor Array
I''m having trouble understanding how high ESR affects the charging current of supercapacitors. I also need some equations to help clarify this. I''m using a supercapacitor array: 7
Supercapacitor minimum voltage
The question doesn''t contain a link to a specific datasheet for a Lithium Ion supercapacitor, but looking at the example for the CAP-XX LY13R8 RADIAL LEAD LITHIUM-ION
capacitor
A supercapacitor or Electric double-layer capacitor (EDLC) is functionally no different from a polarized capacitor, at the schematic level-of-abstraction. Hence, there is no standard symbol for it
ESP32 charging circuit from RPI with supercapacitors
I''m working on a small project and would love a sanity check on my schematic (will attach below) — especially from anyone experienced with ESP32 power design and supercapacitor setups.
Can you safely exceed the nominal voltage of a supercapacitor?
From what I found the data sheets usually only specify the nominal voltage, not Absolute Maximum Value or similar. I need to use supercapacitors for a project where they will run for a total
