The bulb is dim.Because,the voltage is drops in series connection so you add more bulbs in series the last bulb got low voltage that reason for the bulb is dim
We did this experiment in class, the more batteries added, the brighter the bulb will become!
When a bulb is added in parallel to a circuit with a single bulb, the resistance of the circuit decreases. This is because the existing bulb's operating point remains the same, due to the fact that Kirchoff's voltage law states that the signed voltages around a series circuit must add up to zero, with the two bulbs being their own series circuit. A consequence of this is that the voltage across both bulbs must be the same, i.e. that the voltage across the first bulb does not change. The second result of adding the bulb is that the current in the overall circuit increases. This is because the second bulb must pull some current in order to operate, yet we know that the voltage across the first bulb did not change. As a result, due to Ohm's law, the current through the first bulb did not change. And, finally, since Kirchoff's current law states that the signed sum of the currents entering a node is zero, the addition of a second load in parallel with the first load must, therefore, represent additional current.
If a rheostat is connected in parallel with a light bulb, the setting of the rheostat should have no effect on the performance of the light bulb, as long as the power supply is able to maintain its output voltage and deliver the current demanded by their parallel combination.

Switch
to complete the circuit you have to add 1 light bulb.
death 2 the bulb
The bulb becomes brighter unless it is too much till it shot-circuits.

That will depend on whether they are added in series or parallel.
You can make a bulb shine with a fainter light by reducing the voltage supplied to the circuit. This can be done by adding a resistor in series with the bulb to limit the current flowing through it, or by using a dimmer switch to adjust the voltage. Decreasing the power to the bulb will result in a dimmer light output.
When you add a light bulb, you are adding a load, which performs a function - in this case, it converts electrical energy to light and heat energy. When you add an ammeter, most of the time you intend to measure the current in the circuit, which is the function of the ammeter. Thus the two electrical components differ in their function and does different things when added to a circuit.
Adding more batteries to a simple circuit will increase the voltage supplied to the bulb. This will cause the bulb to become brighter as it receives more electrical energy. However, if the voltage exceeds the bulb's maximum rating, it may burn out.
ANSWER: The brightness of both bulbs will decrease. If the bulbs are identical the current will decrease to 0.2 Amps. This is a simple series resistive circuit, the more bulbs you add in series both the amperage and bulb brightness will continue to go down.
If you add another battery in series with the first one, then the bulb willglow brighter, and may burn out if you carry things too far.If you add another battery in parallel with the first one, then the brightnessof the bulb won't change, but the battery will last twice as long.
