NettetWe now need to check the power rating of the resistor when the flasher is on. Power is given by P = V 2 R so let's say we want the LEDs very dim when off so we add 1k in parallel and we'll have 58 V across the resistor when on. P = V 2 R = 60 2 1000 = 3.6 W. Obviously a 0.25 W resistor isn't going to be good enough. Nettet24. jan. 2024 · What are you most proud of from this work and why? Who are your closest competitors?
