WebLearn the Power Formula. We’ve seen the formula for determining the power in an electric circuit: by multiplying the voltage in “volts” by the current in “amps” we arrive at an answer in “watts.” Let’s apply this to a circuit example: How to Use Ohm’s Law to Determine Current. In the above circuit, we know we have a battery voltage of 18 volts and a lamp resistance … WebFirstly, instantaneous power is equal to F · v. If we said that F = m · a, and plug that into the instantaneous power, then we would have P = m · a · v. So now we can see that for the power, the mass does matter. Then, the instantaneous speed is a magnitude that is constant by the simple meaning that is in an infinitesimal time interval.
