@Russ. Stated goalpost has always been "Can electric energy be directly measured?" Underlining goal was to improve my understanding. I am not necessarily claiming that an energy meter always measures power, but stating that I don't understand how any meter can directly measure energy. Maybe...
While I don't agree this device measures the absolute energy value, I agree it measures change in energy. I believe my source of confusion related to thinking change of time was the x-axis which isn't the case thus it isn't displaying power. But it still seems to me that it must be monitoring...
Thanks Windadct, i misspoke about my perceived definition of "directly". I acknowledge that I am measuring current and voltage but see that as directly. I feel when I ride my bike, I can measure distance and measure time and measure speed directly. But not the same with energy, and can only...
Hi All!
It has been a while since I studied this this subject. A real long time! My purpose of this question was just to reafirm my understanding.
@sophiecentaur, Yes, integrated is what I need. Actually, just confirmation that such is what I need.
@Merlin3189. Even mass and length are...
Thanks Russ, Sounds like the old meters just measured power, and used this spinner as an integrator. I suppose someone could make some direct monitoring energy meter by comparing the energy to a known energy value (which doesn't sound like a good idea), but I am really interested in "typical"...
I expect that power monitors directly measure the current, voltage change, and maybe phase to directly calculate current power use.
Can electric energy directly be measured, or do meters just calculate power, and integrate it to obtain energy?
Sorry for being dense.
After compressing the spring with my fingers, I wedge my fingers between a crack in a big rock. I do this for many days until I die and decompose and obviously am no longer utilizing any chemical energy, yet still the spring is compressed. My index finger and thumb...
My muscles are doing work and I am using chemical energy maintaining the tension on the spring, but mechanical work is not being applied to the spring?
Hey, I am a rock! Well, maybe not...
Expending energy or expending work? My thought is when I hold it, my muscles vibrate resulting in a force over a distance but I don't get the energy back when the spring oscillates as I act as a dampener.
I take a spring and expend work to compress it with my fingers thereby increasing the potential energy of the spring. After it is at its final compressed state, am I doing work?
To defend my co-worker, he does HVAC every day and probably hasn't dealt with springs for as long as I haven't. That being said, I will be sure to school him o_O
