A student wants to build a circuit with four lightbulbs and one bell. The student wants to place a switch in the circuit so that only one light will still be on and the bell will still ring when the switch is opened.
Which of these circuits should the student build?
A student wants to make a change to the circuit shown below so that when Switch 1 is open and Switch 2 is closed, only one light will be on in the circuit.
Which diagram shows how the student should change the circuit?
A student constructs the circuit shown for a science demonstration.
With the switches in these positions, which lights are on?
