you can make it brighter by adding another battery/cell
The bulb will get brighter
no
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.
The bulb becomes brighter unless it is too much till it shot-circuits.
change the battery
The Shorter the wire the brighter the bulb ! Because if it is short then it get brighter and the more batterie the brighter the bulb ! Or the lower voltage the brighter the bulb !
Adding more batteries increases the voltage across the circuit, which results in a higher current flowing through the light bulb. The increased current generates more heat and light in the bulb, making it appear brighter.
I you wired a light bulb in to the same circuit you have the possibility of over loading the circuit but other than that it would just be brighter.
it explodes
In a parallel circuit, each light bulb would receive the full voltage of the power source, allowing them to burn brighter compared to a series circuit where the voltage is divided among the bulbs.
That does not depend directly on the brightness of the bulb, it depends on the current drawn by the bulb (which depends on the efficiency of the bulb). For example an incandescent bulb will draw much more current than a much brighter CFL bulb or LED bulb. Therefor switching to an brighter LED bulb can make the battery last much longer while switching to a brighter incandescent bulb will make the battery run down quicker.
We did this experiment in class, the more batteries added, the brighter the bulb will become!
