When The Switch Is Open The Bulb Is On When The Switch Is Closed The Bulb Is Off? Light bulbs will be used to indicate the presence or absence of current. Figure 12.1 illustrates both the switches and light bulbs. The simplest circuit that can be built contains a power supply, a single switch, and
What Does It Mean When A Switch Is Normally Closed? The switch would keep the circuit closed when it has not been pressed. Once it is pressed it will open, causing the circuit to break and the power to be cut. What is the difference between normal open and normally closed switch? Normally open –
What Happens When A Switch In A Circuit Is Opened? A switch in the open position disconnects the light bulb from the battery, creating an open circuit. Turning the flashlight on by sliding the black button to the left pushes the two pieces of metal together — or closes the switch — and completes the
What Happens If A Switch Is Closed In A Circuit? If the switch is closed, the light operates. When a second 60 watt bulb is added to the circuit in parallel with the first bulb, it is connected so that there is a path to flow through to the first bulb or a path to
