-- increase the voltage across its terminals
-- coat the inside with a brighter phosphor
-- clean the outside of it
-- mount a flat mirror or parabolic half-shell behind it
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 !
you can make it brighter by adding another battery/cell
it explodes
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.
Usually a higher voltage will make a light bulb shine brighter; but if the voltage is too high, this can also destroy the light bulb.
Wipe it with cloth I guess?
shut up you nerd
Increasing the amount of electrical current flowing through the bulb's filament will make it shine brighter. Additionally, using a higher wattage bulb or a bulb with a higher lumen output will also produce a brighter light.
Using a shorter wire with the same resistance would result in a brighter bulb, as there would be less electrical resistance in the circuit, allowing more current to flow through the bulb. This would make the bulb emit more light.
If the current is stronger then the bulb will be brighter.The reading is much easier when you sit under the brighter bulb.
more battery's or a better bulb.
