If switch S is opened, the current through bulb 2 will decrease and eventually stop flowing because the circuit is broken. Bulb 2 is connected in parallel to bulb 1 and both bulbs have the same voltage across them, so when the circuit is opened, current stops flowing through both bulbs.
What else can I help you with?
When a circuit is opened what happens?
Nothing. An open circuit means no current is flowing. When the circuit is closed, current flows, the filament of the bulb is heated by the current and glows, giving off light. But when the circuit is open, nothing happens.
What happens when a switch circuit is opened?
When a switch is closed the path through the circuit is continuous.
Does a switch disconnect part of or all of a circuit?
A switch disconnects part of a circuit by interrupting the flow of current through a specific path when it is opened. This can isolate certain components or sections of the circuit while allowing others to remain operational. When the switch is closed, it completes the circuit, allowing current to flow through the entire path.
How does a circuit turn a switch on and off?
A switch makes a physical break in the electric circuit. With the circuit broken the electricity can not flow. When the switch is turned the other way the circuit is completed and the current/electricity can flow.
When the switch is closed electricity will flow through the iron nail the iron nail will become?
When the switch is closed, electricity flows through the iron nail, causing it to become an electromagnet. The flow of electric current generates a magnetic field around the nail, magnetizing it temporarily. This allows the iron nail to attract ferromagnetic materials, such as small metal objects. Once the switch is opened and the current stops, the nail will lose its magnetism.
What happens when a switch in a current is opened?
current through the switch become 0.and switch become a high value resistor.
What happens when a switch a current is opened?
current through the switch become 0.and switch become a high value resistor.
What happens to an electric current at a switch?
At a switch, the electric current can be opened (turned off) or closed (turned on) depending on the position of the switch. When the switch is opened, the circuit is broken, and no current flows. When the switch is closed, the circuit is complete, and current can flow through the circuit.
What happens when we switch on the tube light does current flow through it or voltage?

What happens when a switch is in a circuit is opened?
it prevents electricity to flow. i hope that is right
What happens if the switch is open?
If the switch is open, current does not flow.

When the switch is closed the iron rod becomes an electromagnet?
When the switch is closed, an electric current flows through the iron rod, creating a magnetic field around it. This magnetic field magnetizes the iron rod, turning it into an electromagnet. When the switch is opened, the current stops flowing, and the rod loses its magnetism.
What happens when a switch in a series circuit is opened?
it prevents electricity to flow. i hope that is right
What is happening when a switch is off?
When the light switch is turned on and a light bulb is connected in the circuit a current will flow through the circuit. Likewise when the switch is opened, the current will stop flowing in the circuit.
