Which of the following best describes an electric circuit that powers a load?(1 point)
Responses
Electric current flows from an energy source directly to the load.
Electric current flows from an energy source directly to the load.
Electric current is generated in a conductor and flows through wires to a load.
Electric current is generated in a conductor and flows through wires to a load.
Electric current flows from an energy source through a conductor to a load and back to the energy source.
Electric current flows from an energy source through a conductor to a load and back to the energy source.
Electric current flows from an energy source through a conductor and back to the energy source.
Electric current flows from an energy source through a conductor and back to the energy source.
The best description of an electric circuit that powers a load is: "Electric current flows from an energy source through a conductor to a load and back to the energy source."
To determine the correct answer, we should analyze each option:
1. "Electric current flows from an energy source directly to the load."
This option does not account for the need for a complete circuit. In an electric circuit, there must be a closed loop for current to flow continuously, so it cannot flow directly to the load without returning to the energy source.
2. "Electric current is generated in a conductor and flows through wires to a load."
While it is true that electric current flows through wires to a load, the statement does not specify the need for an energy source. In most cases, the current is generated by an energy source and then flows through a conductor to the load.
3. "Electric current flows from an energy source through a conductor to a load and back to the energy source."
This option correctly describes the flow of electric current in a circuit. The current starts at the energy source, travels through a conductor, powers the load, and then returns to the energy source to complete the circuit.
4. "Electric current flows from an energy source through a conductor and back to the energy source."
This option is similar to option 3, but it does not mention the load. The load is the component in the circuit that consumes the electric energy. So, option 3 is more accurate.
Therefore, option 3, "Electric current flows from an energy source through a conductor to a load and back to the energy source," best describes an electric circuit that powers a load.
