Trying to work out how many atoms of Technetium-99m there are in a 10 MBq dose?
Basically trying to work out if the actual weight of the Technetium-99m will affect the "flight" properties of an aerosol labeled with Technegas. Or would it be negligible?
Basically will using Technegas to...
Hi, I plan to make a simple 12v-battery trickle charger wind turbine that I will put on the roof of my garage and connect to my jetski to keep it topped off during winter when my solar panel is performing poorly.
I have a 24v Motor I will use and will use a bicylce wheel for the "blades". I was...
Hi, I am building a cart for my dog to pull around. I am going to put my child in it once they are about 1.
Something like this.
The paths we plan to go on though are not very smooth so I want to fit some suspension to the cart to make a smoother journey.
Now the weight of the cart will be...
The more I think about it, the more I think about Einsteins conservation of energy law. I think the energy is going to be the same, no matter what I do. Doesn't matter if I give "x" amps at "x" volts or "y" amps at "y" volts. The energy I am putting into the battery will be the same. So Einstein...
I haven't measured the current. I just assumed it is very low because...well, its a small solar panel operating in Scotland on a cloudy day lol.
A won't lie, a lot of this is going over my head, (I don't really have much knowledge about electrical physics).
Was just essential wondering if more...
I was just looking at this guy http://www.ebay.co.uk/itm/1PCS-Output-1-25V-35V-DC-DC-Buck-Converter-Step-Down-Module-LM2596-Power-Supply-/271528251706?pt=LH_DefaultDomain_3&hash=item3f3858513a
It doesn't state the current output, it "claims" 1.5W but as we know it will be very variable depending on sunlight. This is it http://www.amazon.com/dp/B000R0UBT8/?tag=pfamazon01-20
The amps are very very low, just a trickle charge. Basically wondering if increasing the amperage with lower...
Thank you for your reply and forgive my ignorance. So I'm right in thinking, by halving the voltage I'm doubling the current? Now, would this be better at charging the battery? Or because "P" is still "P" will it not make a difference? Thanks.
Hi, I recently bought a smallish 12v DC solar panel for trickle charging my jetski battery. I've had a look at the panel with a multimeter and in good sunlight it makes easy 24V but very very low current. I was wondering if I stick a 99pence buck converter on in, forcing the voltage to a max of...
