WebA 9V battery might start off with, say 5 ohms of internal resistance, reaching over 100 ohms when discharged (figures are rough guide, not researched exactly). If we took a moderately discharged 9V battery (internal resistance risen to 50 ohms) and read with a multimeter (a load of say 1 megaohm) we might read around 9V still, as the multimeter has almost no … WebApplying 9V from your hand to hand directly in your bloodstream would then give 30mA DC which is highly unlikely to kill you. What if you applied the battery straight on your heart? We know the resistance hand to hand is about 300ohms. The length is about 150cm+- and we use 10cm for the heart, reduce to ~20ohms. I = 9V/20 = 450mA.

Web5 Nov 2013 · To use the LEDs without a resistor, you connect all 3 in parallel across 3 V (a 3.3 V coin cell battery, or 2xAA batteries in series). Any higher voltage will burn the LEDs out. Any lower and they probably won't light up. Similarily, you could probably get away with connecting 3 LEDs in series across a 9V battery, but I wouldn't recommend it. Web5 Nov 2013 · Let's say for sake of example you have a typical 20 mA green LED that drops 2.1 V. The battery puts out 9 V, so that leaves 9V - 2.1V = 6.9V accross the resistor in series with the LED. These LEDs can take 20 mA of current, but unless you expect to use it in a bright environment that will be overkill. Let's aim for about 10 mA LED current.
