What else can I help you with?
Does the resistance of a filament light bulb change as the bulb gets brighter?
Yes, the resistance of a filament light bulb increases as the bulb gets brighter. This is due to the increase in temperature of the filament, which causes the resistance to go up.
What happens to a bulb when you move it closer to a battery on a circuit?
The bulb will get brighter
Out of the two bulbs in the house one glows brighter than the other which one of the two has a larger resistance?
The bulb that glows brighter has a smaller resistance. This is because a larger current flows through the bulb with smaller resistance, resulting in it glowing brighter.
How can you make a bulb in a circuit brighter?
you can make it brighter by adding another battery/cell
Suppose in a circuit with 2 bulbs the resistance of bulb 1 is greater than that of bulb 2. how will the voltage across the two bulbs compare?
if the resistance of bulb A is 2x that of B then there will be twice as much voltage across it (ratio 2:1 ). both voltages shall equal the system voltage assuming they are in series and there are no other components in the circuit if the bulbs are in parallel the voltage across them will be equal and that of the system
What will happen to a bulb if you add more batteries to a simple circuit?
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.
Why does a 25 watt bulb glow brighter than 60 watt in a series circuit?
Because the filament of a 25-W lamp has a higher resistance than that of a 60-W lamp and, therefore, will experience a greater voltage drop -the lamp with the voltage drop closer to its rated voltage (in this case, the 25-W lamp) will be the brighter.
A 40W bulb or a 60W bulb will glow more brighter if connected in series?
Oh, dude, let me break it down for you. If you connect a 40W bulb and a 60W bulb in series, the 60W bulb will glow brighter because it has a higher wattage rating. It's like having a race between a tortoise and a hare - the hare (60W bulb) is gonna shine brighter than the tortoise (40W bulb). So, yeah, the 60W bulb takes the spotlight in this series connection scenario.
Will the current in a light bulb connected to a 200-v source be greater or less than when the same bulb is connected to a 110-v circuit?
The current in the light bulb will be greater when connected to the 200-v source compared to the 110-v circuit, assuming the resistance of the light bulb remains constant. This is because current is directly proportional to voltage in an electrical circuit according to Ohm's Law (I = V/R), so a higher voltage will result in a greater current flow through the bulb.
Two light bulbs of resistance R1 and R2 R2R1 are connected in series Which is brighter?
The brightness of a light bulb is related to its power. In all electrical circuits, power is equal to Voltage*Current. Since the two bulbs are connected in series, they must have equal current. The voltage across any given element in a series circuit is proportional to its resistance, so whichever bulb has the higher resistance has a higher voltage and thus higher power and is brighter.
What will happen to a bulb when you move it closer to the battery on a circuit?
When you move a bulb closer to the battery in a circuit, it will receive more electrical energy as the resistance decreases. This will cause the bulb to shine brighter due to the increased flow of electrical current passing through it.
Do two light bulbs in a series circuit have the same brightness?
yes but they will each be less bright then if there was only one light bulb in the circuitAnswerIt depends on their power ratings. If they are different, then the lamp with the lower power rating will be the brighter. The reason for this is that lower power lamps have a greater resistance than higher power lamps and, so, a greater voltage drop appears across the lower power lamp, making them brighter.
