What condition must be met for the switches to be considered closed?
Understand the Problem
The question is asking about the condition for switches to be considered closed, with $x_i$ representing the state of the switch. We need to select the option that mathematically defines a closed switch.
Answer
A closed switch allows continuous electricity flow, completing the circuit.
A switch is considered closed when it allows a continuous flow of electricity, completing the circuit.
Answer for screen readers
A switch is considered closed when it allows a continuous flow of electricity, completing the circuit.
More Information
A closed switch provides a path for current to flow, while an open switch interrupts the current.
Tips
A common mistake is thinking a closed switch means the device connected to the circuit is off; a closed switch simply means the circuit is complete and electricity can flow if other conditions are also met.
