How could you make a light bulb in a circuit brighter?

Answer 1

-- Without changing the bulbs, increase the voltage of the battery or power supply.

-- If the bulbs are in series, take one out of the circuit, and replace it with a piece of wire.

-- Replace incandescent bulbs with others whose filaments have lower resistance.

-- Replace incandescent bulbs with fluorescent tubes.

-- Replace incandescent bulbs with LEDs.

Answer 2

You can make a light bulb in a circuit brighter by increasing the voltage supplied to the bulb. This will cause more current to flow through the bulb, resulting in increased brightness. Just be cautious not to exceed the voltage limit of the bulb to prevent damage.

Answer 3

There is no real way that i know of to make the actual bulb brighter apart from certain ballasts for hps (high pressure sodium lights) have a booster button that can increase the light by about 10%. Your surest bet to get more light is to use a reflector, problem is it doesn't make the bulb brighter, it just targets the light where you want it so you don't lose light by it going where you don't want it.

Using an incandescent lamp, by increasing the voltage will increase the light output.

Answer 4

You can increase the voltage sent to the bulb (up to the limit of the design of the bulb before it breaks).

The light output is a factor of:

1) the voltage across the filiment

2) the resistance of the filament

3) the composition and design of the filament

4) the type of gases inside the envelope.

Answer 5

As we connect cells in series the voltage of each cell got added and as a result the current through the coil of the bulb increases resulting increased brightness.

for series circuit,

V=V1+V2+V3+...

I=V/R

So as v increases, I increases. As a result brightness increases.

Answer 6

A bulb can be made to glow brighter by increasing the voltage that is supplied to the bulb.

Answer 7

By putting another battery/cell.

Answer 8

add more batteries

Answer 9

add another bulb

Answer 10

shorten the wires
