How many amps is 3.7 volts? If you are not sure, don’t worry! This blog post will help you figure it out so that you can confidently answer them the next time someone asks you this question.
How Many Amps Is 3.7 Volts?
In order to figure out how many amps is a certain amount of volts, you need to use Ohm’s Law. This law tells us that voltage = current x resistance. In this case, the “current” would be our amp measurement and we can replace that with Volts/Ohms in order to solve for what we want. Volts/Ohms is equal to amps.
You can also use the equation V=IR which you may remember from your physics class (Voltage = Current x Resistance). Using this equation, you would replace Voltage with I (Current) and replace Resistance with R (Resistance).
That will give you I=V/R, meaning that Current equals Voltage divided by Resistance. We already know what voltage we are dealing with because it was stated in the problem statement so now all we need to do is figure out our resistance which takes us back to Ohm’s Law where R=volts/Amps or volts/(amps*ohms) if substituting for Amp(s) like in the original question.
If you have a digital multimeter, you can measure the resistance of your device to find out how many amps it is. If this isn’t something that you have access to or are able/willing to do for whatever reason, there is an alternate method called “estimating”.
With these methods, you can answer the question of how many amps is 3.7 volts. You can also check our post about demagnetizing metal with a battery.
