If the switch is closed will the light bulb glow.Motivate your answer.
To determine whether the light bulb will glow when the switch is closed, we need to consider the basic principles of an electric circuit.
When the switch is closed, it completes the circuit, allowing the flow of electric current. A closed circuit means that there is a continuous path for the electric charges to move from the power source (e.g., battery) through the conducting wires and into the light bulb.
For a light bulb to glow, it needs a complete circuit and a source of electric energy. The electric current passing through the filament of the bulb generates heat, causing it to glow and produce light. Therefore, if the circuit is closed and the light bulb is functioning properly, it will glow when the switch is closed.
However, there are a few factors to consider that may prevent the light bulb from glowing even when the circuit is closed. These factors may include a blown fuse, a faulty switch, an open circuit due to a broken wire, or a burned-out filament in the light bulb. It is crucial to ensure that all components of the circuit are intact and functional for the light bulb to glow when the switch is closed.
In conclusion, assuming all components of the circuit are in good working condition, when the switch is closed, the light bulb will indeed glow as a complete circuit will be formed, allowing the flow of electric current necessary to generate light.
To determine if the light bulb will glow when the switch is closed, we need to consider the functioning of a simple electrical circuit.
In this case, when the switch is closed, it connects the two terminals of the light bulb together, completing the circuit.
For a light bulb to glow, it requires a complete circuit and an electrical current to flow through it. When the circuit is complete, the current from the power source (battery or generator) can flow through the switch, then through the light bulb, and back to the power source.
Assuming there is a power source connected to the circuit and the light bulb is in working condition, when the switch is closed, it allows the current to flow through the circuit. As a result, the light bulb should glow.
However, it's important to note that if there is a problem with the power source, such as a dead battery or disconnected wires, the light bulb may not glow even if the switch is closed. Additionally, if the light bulb is faulty or burned out, it will not glow regardless of the condition of the switch.
