Which draws more current a 100w

The smaller filament has less resistance which allows for more current to flow. More current, more heat, more light. A zero watt bulb is considered a bulb who's filament has broken. With an open circuit no current will flow. With no flow of current there will be no circuit power. So the answer will be zero consumption for a bulb with no filament.

A 75 bulb will use more electricity. Assuming they both run at the same voltage, the one with less resistance will draw more current and more power. They both consume the same amount of electricity. The v bulb will use less current. Some CF and LED bulbs are rated by the amount of light that an incandescent bulb would produce, but they are also rated by the wattage that they use.

So, with a V mains, a 60W bulb draws 0. On a V mains, a 60W bulb draws. It just draws less power. A watt light bulb draws a little less than one amp.

A refrigerator draws much more when compressor is running. The duty cycle of the light and refrigerator will ultimately determine which uses more power on a Kilowatt Hour basis.

The higher the wattage the more you pay for power. So it costs more to operate a watt bulb than it does a or 40 watt bulb. Because it takes more current and power and produces more light power. Running a w lamp costs 4 times more than a 25 w lamp. Compare to a watt bulb, what is the wattage for a laptop? The difference between the power of a watt bulb and a 75 watt bulb is 25 watts.

A watt bulb will burn about 25 percent brighter than a 75 watt bulb. Log in. We use Watthours is a measure of energy and watts is a unit of power.

Ben Davis November 22, Which has greater resistance a watt bulb or a 60 watt bulb? What is the resistance of a lightbulb? What happens to the resistance of the bulb as the brightness and temperature increases?

What is the resistance of a light bulb that uses 15 watts of power? What happens to the resistance of the filament in a light bulb? What happens to the resistance in the bulb as the current increases? Do you expect the resistance of a light bulb to remain constant? What happens to the current in the circuit as the resistance increases? What happens when you decrease the resistance in a circuit?

However, if the resistance of a parallel circuit is not equal throughout it could cause the brightness to be inconsistant. In saying, this the advantage to a series circuit be that they would have an even brightness throughout. The hundred watt bulb will require more power then the seventy-five watt bulb and both light bulbs will be receiving the same voltage so, that means that the current would have to be larger on the hundred watt bulb. This means the one with the lower power or the seventy-five watt bulb would have the greater resistance.

The reason why replacing a fifteen A fuse with a twenty-five A fuse is dangerous is simple. A fuse is meant to prevent the device from overheating and causing any damage to the device or the surroundings. By increasing to a twenty five A fuse your chances of it burning out are less likely but, there is a huge downside your risk of overheating is increased by a considerable margin. The reason that the fifteen A fuse is blown repeatedly is because you are running too much power through that device and it is breaking as a safety precaution to prevent the wires from heating up to much which could lead to a fire or an electric discharge.

It is a lot safer and smarter just to keep replacing the fifteen A fuse then to take the added risks of the twenty five A fuse.

There are both advantages and disadvantages to having Christmas tree light that are in a series circuit or ones that run in a parallel circuit. If it is in a series circuit then the lights will be at the same level of brightness throughout due to the fact that each light will have the same current.

However if one of the bulbs were to burn out or just die then the rest of the lights would go out since the electricity no longer has the full path to travel.

If it is in a parallel circuit then the lights would get brighter as the chain when on since after each bulb the next one would have less resistance. Another advantage is that some of the lights could burn out and then rest will still function since it is a parallel circuit.

A disadvantage is that since the resistance is lower as the chain goes on this means that the current and the power would increase which could limit how long you could make it since if it were too long then the bulbs would just burn out.

The w light bulb will draw more current since the power is directly proportional to the current. But, the 75w will light bulb has a higher resistance because power is inversely proportional to resistance.

It is dangerous to replace a 15 A fuse that blows repeatedly with a 25 A fuse because the 15 A is the fuse suited for that certain utility. Therefore, if there is a fuse higher than 15 A placed in that slot there could be damage done because this means that there will be more current running through that system than if the system is not able to handle that high of a current it can be dangerous by affecting that utility.

The advantages and disadvantages to connecting Christmas tree lights in a series circuit, and a parallel circuit are, that in a parallel circuit the Christmas lights would be brighter and they would also be able to stay lit even if a couple of light bulbs were to burn out. A higher watt bulb allows more electricity through, therefore the resistance must be lower. It is the product of the current and the resistance that generates the heat not only the resistance.

So although a W lightbulb has a lower resistance, it will have a much larger current due to the low resistance. A watt bulb has a higher electrical resistance than a watt bulb. Because power is inversely proportional to resistance, when the power is less, the resistance is high. Hence, 80W bulb will glow brighter than W bulb when connected in series. So if a package for a lightbulb says the bulb uses 60 watts, or 60W, it means that that bulb will use 60 watts of electrical power.

Typically, the higher the wattage, the higher the lumens, and the more light output. To find which bulb will glow brighter we need to find the power dissipation across each of them. Hence 60W bulb will glow brighter in parallel connection. This is kilo watt hour unit of energy. Supply voltage being constant the more watts means more current,So you consume more energy pay for money. Since a bulb glows brighter when it gets more power the ones in parallel will glow brighter.

See, the parallel combination of resistors reduces the effective resistance of the circuit. Hence it glows brighter. Being in series, same current passes through both the bulbs.
