I am constructing a system in a solar car, and need to have capaitors large enough to power the Telemetry system for about 15s after power down.
I need to use capacitors instead of the batteries, due to race regulations.
The Telemetry system takes about 1 amp at 5v leading to a power consumption of approximately 5 watts. The minimum operating voltage is about 4.5 volts.
I am thinking of using a 5 farad capacitor, but I don't know if this will work. Could someone please shed some light on how this is calculated?
