Study Notes
Electric Current and Potential Difference
- Electric charges flow in a conducting metallic wire due to a potential difference, also known as voltage, between two points in the wire
- The potential difference in a battery is generated by a chemical reaction between the electrolyte and electrode materials
Flow of Electric Charges Analogy
- The higher level tank in the analogy of flow of water represents the higher potential end of the wire, where the electric potential is greater
- In this analogy, the flow of water represents the flow of electric charges in a conducting wire
Gravity and Electric Current
- Gravity does not play a role in the flow of charges in a conducting metallic wire
Connecting a Cell to a Circuit Element
- When a cell is connected to a conducting circuit element, such as a wire, it creates a closed circuit, allowing electric charges to flow from the higher potential end to the lower potential end
