How is an electric circuit described as a physical structure?
AA single wire that stores charge permanently without moving
BA device that converts alternating current into light only
CA region of space where no current is ever present
DA physical network of paths through which electric current can flow
Answer & Solution
Correct answer: D. A physical network of paths through which electric current can flow
1. An electric circuit is defined as a physical structure that guides current.
2. It is specifically described as a physical network of paths through which electric current can flow.
3. Storing charge permanently and converting current to light describe capacitors and bulbs, not the circuit itself.
