isn't that what the jumper cables in the trunk of my car are for?????
"I just like expressing Ohm's law differently..."
RFLMAO!!!!! which one of you has the correct understanding of the "law"?????? Or is it flexible depending on context, presence of alters, cycle of the moon etc?????
sorry....I just couldn't resist!!!! I think the only reason we havn't heard from Steve yet is that the poor man probably bit his tongue off laughing!!!
LK, you are so right, it did bring a smile to my face and my tongue is still sore! Before I came to work here, I was always in the modders forum and one of the best (and heated, no pun intended) discussions we had was about this subject. In fact, if you have lots of time just do a search on Ohms Law.
The great thing about Ohms Law is that it is a law
.that means that it always works the same, every time. When I received my degree in applied electrical engineering 30 some years ago there was no internet and we had to know ohms law without looking it up, and yes I had to walk to school uphill both ways, lol
Below is just part of one of the posts about Ohms Law. Trust me, most of you dont need to read this
or even care. Please understand that a lot of thought has gone into battery voltage, the switch design, and the cartomizer resistance to balance the enjoyment and reliability of your SS!
First thing should be Ohms Law
A good on-line Ohms Law calculator is this one:
Ohm's Law Calculators
If you are old school like me, you can just use your calculator or slide rule.
Before we begin we have to understand a few terms.
E Electromotive force,is a difference in charge that is stored as electrical potential energy known as EMF. It is EMF that causes current to flow in a circuit. Some people call this voltage. It is measured in Volts.
E is a potential energy, it does not do any work and in our case it does not make heat, cause the e-liquid to vaporize, or give throat hit. An easy way to think of EMF is to think of it as water pressure in a hose. Water pressure does not get you wet, water your flowers, or fill up your pool.
R Is the electrical resistance of an object. It is a measure of its opposition to the passage (or flow) of a electric current. Think of this as a water valve. As you open or shut the valve more or less water flows. Again R alone does no works for us or heats up the atty. R is measured in Ohms.
I Electric current is a flow of electrons or the rate of flow of electrons through a conductor (wire, resistor, switch, atty
.). In an E-cig, this flowing electric charge is carried by moving electrons. It is measured in Amps. One amp equals about 6.242 × 10 to the 1018 electrons flow past a given point per second. The electrons flowing through the atty wire is what heats up the atty, causing vapor and throat hit.
I know that what I just said is Electronics 101 for a lot of you, but we need to understand that electrons flowing through the atty are what we care about.
Now that we know that electrons flowing through the atty causes heat, what can we use to compare all the different voltages and different atty resistances that e-cigs have, to see how much heat these different variables can make at the atty?
I suggest we use The WATT. The WATT is the measurement of the rate of energy conversion, or in the case of an e-cig, how much energy does the atty consume or turn into heat. In an atty, that consumed energy is converted to heat. In an atty, heat is all we care about. I do not care what the voltage is, what the atty resistance is, or what the current through the atty is as long as it does not burn out. I care about how many watts the atty is using or how much heat the atty produces, because heat equals throat hit and vapor.
