select all the circuits in which electric current would flow.

select all the circuits in which electric current would flow.

Answer

Brief Explanations:

For electric current to flow, a circuit must be a closed, complete loop with a power source, and no breaks in the wiring.

  1. Top-left circuit: It is a closed loop with a power source, fan, and closed switch, so current flows.
  2. Top-right circuit: It is a closed loop with a battery, closed switch, and component, so current flows.
  3. Bottom-left circuit: It is a closed loop with a power source, closed switch, and component, so current flows.
  4. Bottom-right circuit: There is a break in the red wire, so the loop is open, and no current flows.

Answer:

  • Top-left circuit (with the blue fan)
  • Top-right circuit (with the battery and small component)
  • Bottom-left circuit (with the power source and small component)
