What happens to d cells when they are left connected to a light bulb for a long time?
When d cells (dry cells) are connected to a light bulb for an extended period, they gradually discharge their stored chemical energy, resulting in a decrease in voltage and current output. As the chemical reactions inside the cells proceed, the internal resistance increases, leading to diminished performance. Eventually, the cells may become depleted and unable to supply sufficient power, potentially leaking or corroding if left in a circuit for too long. It is advisable to disconnect them when not in use to prolong their lifespan.

Describe the energy transformations that take place when a battery is connected to a light bulb in a series circuit?
The battery connected to the bulb has the potential chemical energy in it when it is connected by means of wire to the bulb the chemical energy in the battery is converted to the electrical energy which flows through the wire to the bulb glows the bulb which is a form of light energy after some time the bulb starts emitting heat which is heat energy.
Suppose you have a number of light bulbs connected on a circuit with each bulb on a separate branch what happens if one of the bulbs burns off?
As they are connected in parallel (each has its own branch) the remaining bulbs keep shining exactly as they did before.
Why does the light from a bulb connected to a simple cell dim and evengeventually goes off after a while?
The light from a bulb connected to a simple cell dims and eventually goes off due to the depletion of the chemical energy within the cell. As the cell operates, the chemical reactions that produce electricity gradually consume the materials inside the cell, reducing the voltage and current supplied to the bulb. This results in decreased brightness until the energy is completely depleted, causing the light to go out.
What happens when you burn a light bulb?
When you burn a light bulb, the heat generated can cause the filament inside an incandescent bulb to melt and break, leading to the bulb's failure. In fluorescent bulbs, the gas inside can become unstable and release toxic substances. Additionally, the glass can shatter due to the intense heat, posing a safety risk. Overall, burning a light bulb is dangerous and can create hazardous conditions.
Is it burned-out or burnt-out light bulb?
bulb light burned out every 4 months.type of bulb is H7
Can a tomato glow when connected to a light bulb?
No, a tomato cannot glow when connected to a light bulb. Tomatoes do not have the ability to produce light on their own, so they cannot glow like a light bulb.
How must the light bulb be connected in order for it to light up?
The light bulb must be connected in a closed circuit with a power source, such as a battery or electrical outlet, for it to light up. This means that the positive terminal of the power source must be connected to the positive terminal of the light bulb, and the negative terminal of the power source must be connected to the negative terminal of the light bulb. This allows the flow of electricity to power the light bulb and make it light up.
Did the light bulb light up when the dry cells were connected in parallel?
If dry cells are connected in parallel, they will supply more current to the bulb, which will cause it to glow for a longer period of time, but at the same brightness as if only a single cell were used. When the cells are connected in series, the voltage is increased, which will cause the bulb to burn more brightly. If the voltage is increased past the safe point for the bulb, its life will be shortened and it may burn out rapidly. In series, the voltages add. In parallel, you essentially have a larger cell of the same type (cell as in battery of one).
What happens when a bulb is switched on?
when a light bulb is switched on it will blown..............
What energy changes take place when a battery is connected to a bulb?
When a battery is connected to a bulb, chemical energy in the battery is converted into electrical energy, which flows through the circuit and into the bulb. The electrical energy is then converted into light and heat energy by the filament in the bulb, allowing the bulb to light up.
How is energy transfered in a simple system?
In a simple system, such as a light bulb connected to a battery, energy is transferred through electrical currents. When the battery is connected to the light bulb, it provides the energy needed for the bulb to emit light. This energy transfer occurs as the electrons flow through the wire from the battery to the light bulb.
Why the bulb is not lighting when one wire or terminal is not connected?
When one wire or terminal is not connected to a light bulb, it is not possible for electricity to complete the circuit. When a circuit is not completed, the bulb will not light. An off switch, for example, breaks the circuit.
What happen when 3 cells of 1.5V is connected to one end of wires then connected to small torch bulb?
Nothing, for electricity to flow there has to be a voltage difference, ie connected from one end of the cells to the bulb, AND from the other terminal of the bulb to the other end of the cells.
What components do you need to make a simple series circuit to light on bulb?
You need a Battery, Light Bulb, Ammeter, Switch.
What happens to the light bulb when extra dry cells are added to the series circuit?
When extra dry cells are added to a series circuit containing a light bulb, the total voltage supplied to the circuit increases. This higher voltage can lead to an increase in the current flowing through the circuit, which may cause the light bulb to shine brighter. However, if the voltage exceeds the bulb's rated capacity, it could overheat and potentially burn out or become damaged. Therefore, caution should be taken when adding extra cells to avoid damaging the bulb.
What is the job of the cells and wires and bulb and switch in a torch?
The job of a bulb is to give off heat and light energy
What happens when a bulb ammeter battery and switch are put connected together?
the bulb will glow and ammeter will show the reading
