I asked a similar question in electronics stackexchange and was told to come here.
I have been told seemingly conflicting information about electrical resistance and heat generation and am looking for guidance.
I have been told that:
An electrical resistor works by applying friction to the electrons passing through it and radiating the removed energy as heat, so the higher the resistance of the resistor, the more heat is generated.
The more resistance a resistor has, the less current will flow through a circuit. Imagine a simple circuit with a 9v battery and a single resistor, the higher the resistance of that resistor, the less current will flow through that circuit and the longer that battery will last.
So in one case more friction equals less current and in the other case, more friction equals more heat.
Something about this seems contradictory to me.
I imagine two circuits. Each with a resistor and a 9v battery.
Circuit #2 has a resistor with 2x the resistance of Circuit #1
I imagine that Circuit #2 will NOT generate 2x as much heat as Circuit #1.
If that is the case, the stronger resistor is slowing the flow of the current without converting the difference entirely into heat.
If that is the case, then the physical process behind electrical resistance must be different than the physical process behind electrical heat generation.
What am I missing here?
Thank you for your time!
