Fill in the blank with one of the two choices. For electricity to flow in a circuit, it must be a complete full loop. Switches can open to break the circuit or close to complete the circuit. If a switch is open making a gap in the circuit, electricity ________________ flow.
What are the choices?
There is no choices.
It says "two choices", however, if there is a gap in the circuit, electricity will not flow.
If a switch is open making a gap in the circuit, electricity cannot flow.
To understand this concept, let's break it down:
- In a circuit, electricity flows when there is a complete path for the current to travel.
- The switch acts as a control device that can either open (break the circuit) or close (complete the circuit).
- When the switch is open, it interrupts the flow of electricity by creating a gap in the circuit.
- Since there is no complete path for the current to travel, electricity cannot flow through the circuit when the switch is open.
Therefore, the correct answer to fill in the blank would be "cannot" flow.
