Is it correct to say that the voltage is converted to heat? Or is it something like, the energy expended by the current flowing through the resistors is equal to the integral of power with respect to time. The power is a function of voltage, current and resistance. That energy is given off as heat.
Energy can do work, for that it needs time.
More work during that time needs more power.
So energy and power are sort of the same.
Electricity can't be forced, it is taken.
Resistance is taking energy of one form and converting it to the other.
Two fluids can't mix if there is a gap.
Electricity can't flow if circuit is not closed.
Flowing electricity is balancing potential differences.
Resistance is resisting electricity flow by creating friction, and heat.
But it's not forcing, only balancing.
After balance there are no more free circuit participants to balance more.
Electricity is on the high ground, it has a potential.
When it drops down its shape decides the rest of its effect.
Medium through what it is dropping decides that shape.
Since electricity is taken, it is also given, if available.
If current is not available voltage must drop, to maintain balance.
Maybe it's demanded.
