It will if the batteries are connected in series. If they are connected in parallel, the lamp will burn longer, but not brighter.
Shut up you fat monkey
A pencil has nothing to do with the brightness of a light bulb.
Increase the voltage supply.
We did this experiment in class, the more batteries added, the brighter the bulb will become!
The brightness of a standard bulb is directly proportional to the amount of voltage drop across the bulb itself. Thus, to increase the brightness :-Pass more current across the bulb by reducing the resistance of the circuitIncrease the voltage across the bulb, or the circuit. Change the supply.
The brightness of a bulb would not change if you added a second bulb in parallel with the first.Unless, of course, the increased current exceeded the power supply's capacity causing a reduction in voltage.
You alter the brightness of a bulb by changing the voltage or frequency that is applied to the bulb.
When you attach more batteries to a light bulb, it increases the voltage across the bulb, which leads to a higher current flowing through it. The increase in current causes the filament in the bulb to heat up more, resulting in increased brightness.
Yes, two batteries will make a light bulb brighter than one, provided that the batteries are placed in series. The brightness of the bulb is determined by the voltage, and placing two batteries in series rather than just using one increases the voltage.
The relationship between voltage and brightness of a bulb is directly proportional. As voltage increases, the brightness of the bulb increases because higher voltage provides more energy for the bulb to emit light. Conversely, decreasing voltage reduces the brightness of the bulb.
Almost none.
That is called a rheostat or a dimmer.
