Electrical power of a bulb is real power used by the bulb. It is measured in Watts. In general, the higher the bulb watt rating, the more lumens it will produce. This is not always the case, since some bulbs are more efficient than others at turning electrical energy into light (ie some bulbs produce more heat, an unwanted byproduct, than others).
Real electrical power is always measured in watts. Total power (real and reactive) is measured in volt amperes, which is a vector summation of real power plus reactive power. Power times a time it is used is measured in Joules, or watt seconds.
What else can I help you with?
Electrical power of light bulbs is measured in what?
Watts.
The electrical power of light bulbs are measure in what?
watt
Electrical power in light bulbs is measured in what?
wattage or watts
The electrical power of light bulbs is powered by what unit?
watts
The electrical power of light bulbs is messured in what form?
decibels
Can mechanical energy power light bulbs?
Yes, mechanical energy can be converted into electrical energy which can then power light bulbs. This is typically achieved through devices like generators which convert the mechanical energy into electricity that can be used to light up bulbs.
What kind of energy does headlights of a car have?
The headlights of a car typically use electrical energy from the car's battery to power the light bulbs. The bulbs then convert this electrical energy into light energy that illuminates the road ahead.
What are three objects that use electrical energy?
Light bulbs: Light bulbs use electrical energy to produce light. Television: Television sets use electrical energy to power the screen and speakers. Laptop computers: Laptops use electrical energy to operate the display, processor, and other components.
How does a light bulb light?
light bulbs have metal contacts that connect to an electrical circuit and a filament. power lights up the filament in the bulb .
How is the electrical power of light bulbs is measure?
By taking the voltage across the bulb and multiply by the current flow.
What is the energy transformation of a traffic light?
A traffic light typically uses electrical energy to power its light bulbs, which convert the electrical energy into light energy. The light energy is then used to signal drivers on the road.
The power pf light bulbs in Measured in?
The power of light bulbs is measured in watts (W), which indicates the amount of energy consumed and the brightness of the light produced. The higher the wattage, the brighter the light emitted by the bulb.
