Question

why can electricity not flow in an open circuit?

Answer 1

It cannot flow in an open circuit because there will be no potential difference b/w the two ends.So, no electrons will flow.Hence no current will flow.
Hope it will help

Answer 2

Electric charge requires a potential difference to flow.

• An electrical circuit requires a potential difference to be applied in order to allow the flow of current in the circuit.
• This is achieved by connecting the two ends of the circuit to the two terminals of a cell or battery. The flow of current is from the positive terminal to negative terminal.
• In an open circuit, there is no potential difference across the circuit as all components are not connected. Hence, there is no flow of electricity (current).
