This varies greatly. A commonly used lamp is low pressure sodium (the very yellow ones). This would likely be 90w (but there are bigger and smaller) so 0.09 X 24 = about 2 kWH per day. The brighter yellow ones are high pressure sodium and would likely be about 150w (again there are bigger so maybe 250w or 400w). The newer white ones are metal halide and probably about the same power as a high pressure sodium with better light. You may find the odd mercury vapor light (white) in older fittings.
What else can I help you with?
When you turn on a lamp electric energy changes to what kind of energy?
When you turn on a lamp, electric energy is converted into light energy and heat energy. The electric current flowing through the lamp's filament generates heat, which in turn produces light.
What type of energy is converted in an incandescent lamp?
Electric energy is converted into light and heat energy in an incandescent lamp. The electric current passing through the filament of the lamp heats it up, causing it to emit light as well as heat.
Which current does a street lamp use ac or dc?
Unless the street lamp is a self-contained, battery-operated, solar-charged model, it almost certainly would be an ordinary AC-powered light.
What is incandescent light bulb?
An incandescent light bulb, incandescent lamp or incandescent light globe is an electric light which produces light with a wire filament heated to a high temperature by an electric current passing through it, until it glows.
What is HIE lamp?
HIE stands for High Intensity Electrode. HIE lamps are a type of high-intensity discharge lamp commonly used for street lighting and outdoor applications. They produce bright, intense light by sending an electric current between two electrodes through a gas or metal vapor.
A bulb in a lamp converts electric energy into?
A bulb in a lamp converts electric energy into light and heat energy.
How is energy transformed in an electric lamp?
In an electric lamp, electrical energy is transformed into light energy and heat energy. When the lamp is turned on, the electrical current flows through the bulb's filament, causing it to heat up and emit light. Some of the electrical energy is also transformed into heat energy due to resistance in the filament.
What was the light bulb originally called?
It was called the T. A. Edison electric - lamp. In Europe it was called the Ediswan lamp.
How does electric lamp function using electricity?
You plug it in and it lights up. Current flowing in the filament makes it white hot, and it emits light.
If an insulator with a lamp is connected in a electrical circuit The switch is turned-on What happens?
If an insulator with a lamp is connected in an electrical circuit and the switch is turned on, the lamp will not light up. Insulators do not allow the flow of electric current, so the circuit will not be completed, and no electricity will reach the lamp to cause it to light up.
Why starter used in tube light fitting?
The starter is used to help the lamp light and acts like a closed switch. It allows electric current to flow through the filaments.
How does the electric lamp function using electricity?
An electric lamp works by passing an electric current through a filament inside the bulb, which heats up and produces light as a result of its high temperature. The filament is typically made of tungsten due to its high melting point. The light emitted is a result of the filament glowing white-hot when electricity flows through it.
