What is series connection of light bulbs?
If only one end is connected to each other, this type of connection is called series connection. As the number of bulbs increases, the resistance will also increase, and the amount of current passing through it decreases. As the number of bulbs increases, the brightness of the bulb decreases. Brightness moves in direct proportion to the current flowing through the bulb.
Does the number of batteries affect the brightness of the bulb?
– Keeping the number of bulbs constant in an electrical circuit, the number of batteries If we increase it, the brightness of the bulb will increase. – If we reduce the number of batteries by keeping the number of bulbs constant in an electrical circuit, then the brightness of the bulb decreases.
How does the light bulb increase the filament?
The filament is made of heat-resistant materials (tungsten) because electrical energy turns into heat, the temperature rises. Accordingly, the resistance and heat resistance of the filament are high. and the other one is attached to the 1, 2 and 3 points of the nail respectively, we see that the brightness of the bulb gradually decreases.
How does the length of the wire affect the brightness of the bulb?
The brightness of the bulb increases as the length of the wire increases. decreases.
Does the current decrease in series connection?
The same amount of current flows through the resistors connected in series and in the same direction.
What is the serial and parallel connection of the generators? ?
It is the potential difference that a battery will provide to the circuit for a longer time. In other words, it is to ensure that the current passing through the circuit continues in the same way for a longer time. In this case, the current supply capacity of the circuit is increased. If a battery in the circuit runs out in one hour, two identical batteries connected in parallel will run out in two hours.
How does the brightness of the bulb change as the number of batteries increases?
The increase in the number of batteries has increased the brightness of the bulbs. Because a light bulb is illuminated with more battery energy instead of one battery energy. In this case, the intensity of the light given by the bulbs has increased.
What is the reason why the bulb is made of tungsten metal inside?
Tungsten metal is generally used in filament production because it has a high melting point temperature. . The filament made of tungsten metal produces light at these temperatures and provides illumination.
What can happen if the lamp does not light?
If the bulb does not light in a closed circuit, the battery used may be empty. If the switch is open in an electrical circuit, it is called an open circuit. Since the electricity from the battery cannot reach the other elements of the circuit, the bulb does not light. The connection cable may not have touched the poles of the battery.
What is the ratio between the number of bulbs and the brightness of the bulb?
The increase in the number of bulbs has reduced the brightness of the bulbs. Because a battery has shared its energy with more light bulbs instead of a light bulb. In this case, the intensity of the light given by the bulbs decreased.
