This board provides a rechargeable power source that can be used to power a project. It works by charging up a 1F super capacitor when it is connected to a USB port. Two LEDs are used to show when the capacitor is charged (this takes about 1 minute).

Once charged the USB lead can be removed and the board used as a power source. The power connection is by two solder connections. When switched on the board provides power until the capacitor is empty. The length of time this takes will depend upon your application circuit (from a few seconds to ten minutes or more).

    Hi Robert,

    The kit as is would only power the amplifier for a second and the 10F for around 5 seconds.

    There wouldn’t be any problem with swapping the capacitor to a larger one, however you would need to take into account the charging time would also increase. So the 1F capacitor takes around 1 minute to charge, so a 10F capacitor would take around 10 minutes to charge.

    Unfortunately the kit wouldn’t be able to power the high torque motor, if you were wanting to use a motor with this kit then we use a low solar motor with the STEM racer kit, https://www.kitronik.co.uk/4501-stem-racer.html

    A:

    The percentage of the voltage drop across the resistor would increase but the current would decrease proportionally  so the power consumed by the circuit as a whole would drop and the power consumed by the resistor would remain the same, though it would be a larger percentage of the total power consumption of the circuit. In fact no value of resistor would generate more heat in that circuit.  A 1 Ohm resistor would let 10 times more current through but the voltage drop would be 10 times smaller so the power dissipated would be the same. A 100 Ohm resistor would have 10 times more voltage drop across it but let 10 times less current through. Same power. The capacitor however would charge more slowly with less current allowed through so it would receive less power and the overall power of the circuit would decrease.

    The key point here is that the voltage drop across the resistor is very small and the voltage drop across the capacitor is very large.   P= IV

     

    For resistor P = 500mA x a very small voltage.

    For capacitor P = 500mA x almost 5V

     If you add both those powers together you get 2.5W.

    The Super Capcitor Charge Controller Kit measures the voltage across the super capacitor and cuts off charging once it reaches the peak voltage of one super capacitor. If you want to charge a bank of super capacitors you'd need a different circuit. Charging whole banks of super capacitors can be more difficult than just applying a voltage across all of them, I'd recommend researching the topic before attempting it or you may explode some capacitors.

    Hi Tom,

    Please take a look at this resource for understanding capacitors in parallel and series.
