Q3: So long as we include both i(conduction) & i(displacement), our definition of a "complete circuit" seems to demand this to be TRUE.
Q4: If we ignore the "thermal energy" that can leave {or enter through thermocouple or Peltier effects) a circuit, this one seems TRUE also.
BTRW: In the context of this question, where should we account for the transport of thermal energy or "mechanical energy" being converted to "electrical energy" and coming into the "complete circuit" from inductive pickup or piezo-electric effect.

The last true/false quiz provoked an interesting discussion.
So let's take another step in that direction. I'll make it
really easy, by telling you where you can look up the answers.
Q3: True or false: Electrical current is conserved. This
means current cannot be "used up".
Knight, page 892 and page 896.
Q4: True or false: In a circuit, energy can be "used up".
Knight, page 896.
