Does a 100w lamp use more energy than two 60w lamps?
NO. Two 60W lamps will use 120W - which is more than 100W !!
Why would a high watt lamp draw more current than a low watt lamp?
Power is measured in Watts, power (Watts) = E (volts) x I (current - amps) current is determined by the internal resistance (R) of the lightbulb, the lower the resistance the more current will flow. 120v x 0.5a = 60W 120V x 0.83a = 100W the 100W lightbulb will draw more current We also have Ohm's law: E(volts) = I (amps) x R (ohms) Household voltage stays the same at 120v we have for a 100w lamp: 120v = I x R R = 120v/0.83 amps R = 144.6 ohms for a 60w lamp: 120v = I x R R = 120v/0.5 amps R = 240 ohms The higher watt lamp has lower resistance.
Can you use a led lamp in a 100w sodium fixture?
Probably not. Sodium light fixtures generally have a "ballast".
How many 100W lamps may a 230V 6A lighting circuit have connected to it?
You can connect a maximum of 2 lamps to a 230V 6A lighting circuit because each 100W lamp will draw approximately 0.43A (100W ÷ 230V = 0.43A), so 2 lamps would draw 0.86A, which is within the 6A limit of the circuit.
What is the lamp compared to in the lamp at noon?
In "The Lamp at Noon," the lamp is compared to a "candle in a wide field" to highlight its insignificance and futility in the vast and desolate landscape. This comparison emphasizes the characters' futile struggle against the harsh natural environment.
Does a 100w lamp use more energy than two 60w lamps?
NO. Two 60W lamps will use 120W - which is more than 100W !!
What is the VA of a 100W metal halide lamp?
For general calculations VA is the same as Watts.

A 2.5 Amperes current flows through a 100W lamp what is the voltage?
The formula you are looking for is E = W/I.
Can you use a led lamp in a 100w sodium fixture?
Probably not. Sodium light fixtures generally have a "ballast".
Which has a higher resistance a 5w lamp bulb or a 25w lamp bulb and how many times?
As per the formula for power (Power (Watt) = Voltage (V) x Current (i) & Resistance (R) = V / i), 25w lamp bulb would have higher resistance compared to that of 5w lamp bulb.
How much electrical energy does a 100W lamp use in 1 second?
Watts measure power. Energy is measured in joules and is the product of power and time. 1 joule = 1 watt for 1 sec Energy used in the example = 100 x 1 = 100 joules
Which bulb will glow brighter two bulbs of rating 100w-220vand200w-220v are connected in a series to a supply of 22ov?
For a lamp to operate at its rated power, it must be subject to its rated voltage. The lower the voltage, the lower the resulting power. In fact, a small drop in voltage will cause substantial drop in power. Higher 'wattage' lamps have lower resistance values than lower 'wattage' lamps.So, if you put two lamps in series, the greater voltage drop will appear across the lamp with the greater resistance. In your example, that means the 100-W lamp will be subject to the greater voltage drop, and its loss of power will be less than that of the 200-W lamp. So the lower power lamp will be the brighter of the two.
100w bulb and 60w bulb connected in parallel to 220v which will glow brightly?
Total supply voltage = 220vrated power of first lamp= 100 wattso current though it, I=p/vI=100/220=.45 ampsResistance offered by first lamp=220/.45= 488 ohms( i avoid fractions)..............................................................rated power of second lamp=60 wattsvoltage is same, so current through it = 60/220=.27 ampsresistance of second lamp = 220/.27=814 ohms( i avoid fractions).........................................................................power drawn by first lamp =I12 R=(.45)2 * 488 =98.82(=100)power drawn by second lamp =I22 R=(.27)2 * 814 =59(=60)...................................................................................SO 100 WATT BULB WILL GROW BRIGHTER AS IT HAS MORE POWER
How many 100W lamps may a 230V 6A lighting circuit have connected to it?
You can connect a maximum of 2 lamps to a 230V 6A lighting circuit because each 100W lamp will draw approximately 0.43A (100W ÷ 230V = 0.43A), so 2 lamps would draw 0.86A, which is within the 6A limit of the circuit.
Can you change a 60W socket to a 100W socket on a table lamp?
Generally speaking, the rated power of any light fitting ('luminaire'), including a table lamp, is determined by the enclosure, shade, or reflector, rather than its socket. What it comes down to is (a) whether the rate of heat transfer away from the lamp is sufficient to prevent the luminaire from overheating, and (b) whether the reflector/shade can withstand the resulting temperature.
