Hi all and Thankyou for being such a helpful group of people.
I’m very much learning, it’s also lockdown (lack of options).
My goal is to understand how long a battery will take to drain with two leds. Circuit is a 5.3v battery, and two leds each with a 1k resistor, parallel circuit. Had them connected a couple of days now. But when I try do the maths for how long the battery should last it’s in hours not days, where am I going wrong?
5.3v battery, 2600mah each led has a voltage drop of 2.6, each resistor is 1k. So total resistance in this circuit is 500ohms (1/r1 + r2 = 0.5 and 2600/500 =5.2
How can that be possible that the battery is still working when the life at this current should be 5.2 hours? Where am I not understanding?
