What consumes more power a light bulb or toaster?
By far a toaster draws more current than a light bulb.
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.
Functions of choke and starter in a fluorescent lamp?
It provides an 'inductive kick' to start the lamp, and also limits current to the proper level after the lamp is started.
Formula between Current and luminous intensity?
Any formula relating those two quantities must depend on the technique used to generate light by means of electric current. We know that there can't be one universal formula because, for example, we know that a compact fluorescent lamp uses less current to produce more luminous intensity than an incandescent lamp.
How much current will the lamp draw from the main line if a lamp is rated 40W and 220V?

How does an electric circuit with a battery lamp copper wire and switch work?
The battery provides the current and the energy; the lamp consumes the energy when the current goes through it; the copper wire conducts the current; and the switch lets you close or open the circuit (so that current passes, or doesn't pass, through).
How is LED different from lamp?
similarity between lamp and LED- lamp in simple current is used to show that current is flowing and LED performs the same task but in electronic circuit .difference between lamp and LED-lamp in simple current is used to show that current is flowing and LED performs the same task more efficiently but in electronic circuit . so LED works more efficiently in electronic circuit than lamp which performs task in simple circuit.
Does a lamp with a thick filament draw more current or less current than a lamp with a thin filament?
A lamp with a thick filament will draw more current. What restricts the current flow in the filament is the resistance of the filament which increases as the temperature of the filament increases. A thin filament requires less energy to get heated up that a thick one so less current to achieve threshold resistance. Also a thick filament provides a broader path for current so there is less resistance per increase in degree centigrade. For these two (closely related but distinct) reasons it will require more current for the filament to get heated up to threshold resistance.
What happens to the current in a circuit if more lights are added?
Assuming you are referring to house lamps, these are always connected in parallel with each other. Each lamp will draw a current, the value of which depends on the wattage of the lamps. As each lamp is added, the supply current will increase by the amount of current drawn by that lamp.
What consumes more power a light bulb or toaster?
By far a toaster draws more current than a light bulb.
Which action would most help a citizen become more informed about current issues?
Recognizing the biases of the media he or she consumes
If a 12 volt parallel circuit has 4 lamps and each lamp consumes 1 amp what is the resistance of each lamp?
Assuming you mean the 4 lamps are in parallel with each other: the total voltage drop across each lamp is still 12V. As we know that V= IR (Voltage = I Current times Resistance) 12 = 1 x R so Resistance = 12 Ohms for each lamp.
When does the lamp on your tv die after the warning?
There is no way to know for certain when the lamp will die, but when the light comes on, the power to the lamp has detected the increase in current, which is indicative of a lamp that is about to burn out. I would purchase a replacement lamp and have it on hand when the bulb goes out. I would expect you will get no more than a couple of weeks use from this old lamp.
Will the current in the light bulb connected to a 220v source be greater or less than when the same bulb is connected to a 110v source?
A: The current is not a function of voltage available but rather the power needed to light the lamp. To answer your question a 100 watts lamp will require 1.83 times more current for a lamp rated as 100 watts at 120 volts.It is a basic ratio 220:120AnswerI disagree with the previous answer. The power rating of a lamp only applies when the lamp is subject to its rated voltage -which is why both values are shown on the lamp (e.g. 60 W / 120 V).So, if you subject a lamp to less than its rated voltage, it will not achieve its rated power. In fact, the decrease in power will be significantly greater than the corresponding decease in voltage. It will certainly not 'compensate' by drawing more current!However, to directly answer your question, the current drawn by a lamp connected to a 220-V supply will indeed be greater than the current drawn by the same lamp connected to a 110-V supply.
Is less current out of a lamp than in?
No.
Does a lamp with a thick filament draw more or less current than a lamp with a thin filament?
A lamp with a thick filament will draw more current. What restricts the current flow in the filament is the resistance of the filament which increases as the temperature of the filament increases.

An incandescent lamp connected to 120 voltage source with a short extension cord provides more illumination than the same lamp connected to the same source with a very long extension cord?
A: absolutely not lamps needs current a long cord introduce IXR drop making less current for the lamp to use it
