True because when the positive and negative connects the bulb glows..! :))
True or false When the positive of bulb is connected with positive of ...
True or False: When the positive of a bulb is connected with the positive of a cell and the negative of the bulb is connected with the negative of the cell, the bulb glows.
Yes, this statement is true. When the positive terminal of a bulb is connected to the positive terminal of a cell, and the negative terminal of the bulb is connected to the negative terminal of the cell, the bulb will indeed glow. This can be explained through the following points:
1. Closed Circuit:
In order for the bulb to glow, there must be a complete closed circuit. This means that there should be a continuous path for the flow of electric current from the positive terminal of the cell to the negative terminal.
2. Flow of Electric Current:
When the circuit is closed by connecting the terminals of the bulb to the cell, an electric current is able to flow. This is because the positive terminal of the cell provides a surplus of electrons, while the negative terminal of the cell has a deficit of electrons. This difference in electron concentration creates a potential difference or voltage between the two terminals, which causes the flow of electric current in the circuit.
3. Bulb Filament:
Inside the bulb, there is a filament made of a material that offers resistance to the flow of electric current. When the current passes through this filament, it heats up and begins to glow. The filament's resistance causes a drop in voltage, which helps to regulate the amount of current passing through it.
4. Polarity of Connections:
Connecting the positive terminal of the bulb to the positive terminal of the cell, and the negative terminal of the bulb to the negative terminal of the cell ensures that the current flows in the correct direction through the bulb. This is important because the filament is designed to work optimally with a specific polarity.
5. Completion of Circuit:
By connecting the terminals of the bulb directly to the corresponding terminals of the cell, the circuit is completed, allowing the electric current to flow continuously. This enables the filament of the bulb to heat up and emit light, resulting in the bulb glowing.
In conclusion, when the positive terminal of a bulb is connected to the positive terminal of a cell and the negative terminal of the bulb is connected to the negative terminal of the cell, the bulb will indeed glow. This is due to the flow of electric current in the closed circuit, the heating of the bulb filament, and the completion of the circuit through the correct polarity of connections.
