Power Grid, L goes up, why grid current goes up as well?

AI Thread Summary
The discussion centers on the relationship between inductive loads and grid current in power systems. It highlights that an increase in inductive load causes voltage drops across those loads, necessitating an increase in grid current to maintain power delivery. The confusion arises from the understanding of how constant power is ensured despite voltage changes. A referenced article from Physics Forums provides insights into voltage control mechanisms that address this issue. The user expresses gratitude for the resource, indicating its significance in their understanding of reactive power.

I am on a perpetual quest to understand reactive power.

one of the road blocks I encountered is this text:
" if inductive load in the grid increases, voltages across loads will drop. In order to maintain power delivered, grid current has to increase"

That statement is quite frustrating to understand. my understanding is that If voltage across a resistive load drops then less power is delivered to that resistive load, who and what mechanism is making sure constant power needs to be delivered to that resistive load?
 
Engineering news on Phys.org
Hey guys. I have a question related to electricity and alternating current. Say an alien fictional society developed electricity, and settled on a standard like 73V AC current at 46 Hz. How would appliances be designed, and what impact would the lower frequency and voltage have on transformers, wiring, TVs, computers, LEDs, motors, and heating, assuming the laws of physics and technology are the same as on Earth?
I used to be an HVAC technician. One time I had a service call in which there was no power to the thermostat. The thermostat did not have power because the fuse in the air handler was blown. The fuse in the air handler was blown because there was a low voltage short. The rubber coating on one of the thermostat wires was chewed off by a rodent. The exposed metal in the thermostat wire was touching the metal cabinet of the air handler. This was a low voltage short. This low voltage...
Thread 'Electromagnet magnetic field issue'
Hi Guys We are a bunch a mechanical engineers trying to build a simple electromagnet. Our design is based on a very similar magnet. However, our version is about 10 times less magnetic and we are wondering why. Our coil has exactly same length, same number of layers and turns. What is possibly wrong? PIN and bracket are made of iron and are in electrical contact, exactly like the reference design. Any help will be appreciated. Thanks. edit: even same wire diameter and coil was wounded by a...
