What is the best way to visualize the flow of electrons in a current?
- Electrons rolling along a wire like a line of marbles
- Electrons powering electrical devices like a turbine
- Electrons being pushed by a battery like a pump
- Electrons flowing like water through pipes (correct)
What is the function of the power source, or battery, in an electrical circuit?
What is the function of the power source, or battery, in an electrical circuit?
- To determine the thickness of the wires
- To control the resistance of the circuit
- To act as a pump, pushing electrons into the pipes (correct)
- To convert electrical energy into mechanical energy
How does the water analogy help in understanding resistance in an electrical circuit?
How does the water analogy help in understanding resistance in an electrical circuit?
- Wider pipes can carry more water, just as thicker wires have lower resistance (correct)
- The turbine's rotation determines the resistance in the water flow
- Narrow pipes have less resistance to water flow, like thin wires
- The pump's power determines the amount of water flow, like a battery's voltage
