When you add more batteries to a circuit what happens to the bulb brightness?

Answer 1

if you put too many batteries in the socket, the bulb will blow out because there would be too much energy passing through the circuit.

If you put too little amount of batteries in, the brightness will be low, and will probably run out, because of the little amount of energy passing through the circuit

the more batteries, the brighter the bulb

Answer 2

The brand of the battery does not affect the ability to provide power to a bulb - or any other load - However......there are brands that have a better consitency of production standards and that WILL affect what the consumer sees when they put in a replacement battery. The best brand that I have found is Duracell.

Answer 3

ANSWER:

If the wire is very long then it takes long for the electricity to reach the bulb so the light in the bulb is dim. But if the wire is short, then you will see that the bulb lights up brightly. But if there is only one bulb and three batteries then the bulb will obviously burst due to the great amount of electricity.

Answer

The first answer is clearly ridiculous, as the length of a conductor has absolutely no effect on the time it takes 'electricity (sic) to reach the bulb'! The ONLY way in which the length of a conductor may affect the brightness of a lamp is if its resistance is high. A longer wire will always have a higher resistance than a shorter wire of identical cross sectional area. The reason for this is that a wire of higher resistance will result in a higher voltage drop along that wire, thus reducing the voltage available across the lamp.

Answer 4

no, (unless the existing battery cannot deliver enough current)

Answer 5

A: Batteries connected in series the voltage add but the current available will be the lowest current capacity as connected
