Question

how does the valve on the cooler compare with the switch in an electric circuit? opening the valve allows water to flow, just like opening a switch allows charges to flow. opening the valve stops the flow of water, but closing a switch stops the flow of charges. closing the valve stops the flow of water, but opening a switch stops the flow of charges. closing the valve allows water to flow, just like closing a switch allows charges to flow.

Answer 1

One thing that must be underlined is :

- Switch is opened to broke the flow of the circuit
- Valve is opened to release whatever it contained inside

So, the most likely relation between valve and switch is  :  Closing the valve stops the flow of water, but opening a switch stops the flow of charges

hope this helps
