Hi folks,
My question relays on the difference of consumption power of a coil when it's on AC and CC regime.
A coil is made of copper wire with an air core, aplied on it a CC current of 1 amp, a measure was taken and nottice a 5W of power consumption. Then the power supply is changed to and AC power supply, now the consumption was about 5,5W. Now the coil was dismade and it is just a simple wire ( straigh line) and remais on AC power supply. Now the consumption is around 5W again.
I have some tought about it but i'm not quite sure. It seems to me that when you a CC regime on a wire, the coil only represent a indcutor it self and after a long time it turn just to be a short circuit, so this cant increase the power.
When i have the coil on AC regime, it creates a self induction made by a opsition to the real currente that pass trough the wire, in that, we need to increase the voltage of the power supply to still with 1 amp (effective).
Can someone help me to understand why this occurs?
