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?
Which energy conversion takes place when a solar cell is used to light a street lamp?
light to electricity to light (plus that old devil heat).
When a lamp is switched off is the electrical current to the light open or closed?
Open and closed does not refer to electrical current or the flow of electricity. Open or closed refers to the state of an electrical circuit. When a lamp is turned on electricity flows through wires, the switch and the lamp; and the circuit is considered closed. When a lamp is switched off the circuit is considered open (or broken) and the flow of electric current is stopped.
What is the energy conversion of lamp?
A lamp converts electrical energy into light energy through a process called incandescence or fluorescence. The electrical current passes through a filament or gas-filled tube, causing it to emit light.
If the ballast on a fluorescent light blows will the lamp still work?
Typically, if the ballast on a fluorescent light blows, the lamp will not work. The ballast regulates the electrical current to the lamp, so if it is not functioning properly, the lamp will not receive the correct power to light up.
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.
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.
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 does a lamp in a circuit do?
A lamp in a circuit converts electrical energy into light energy when current flows through it. This conversion is possible due to the properties of the lamp's filament or gas, which heats up and emits light when electricity passes through it.
What does a filament lamp do in a circuit?
A filament lamp produces light by converting electrical energy into heat and then light. It acts as a resistive load in the circuit, meaning it resists the flow of current and causes the filament to glow and produce light.
What do you use to make a amp or light fitting light up?
A lamp or light fitting will light up if connected to either Alternating Current (AC), or Direct Current (DC). AC is from the mains, and DC is from a battery. So it depends on the construction and components used to construct the lamp as to which electrical source you use.
What type of energy is a lamp plugged in and turned on to light a dark room?
it starts with electrical thats the main one but there is more
How does energy transfer in a lamp work?
In a lamp, electrical energy from the power source is converted into light and heat energy. This transformation occurs when the electric current passes through the filament inside the bulb, causing it to glow and emit light. Some of the electrical energy is also converted into heat energy, which can be felt as warmth when the lamp is on.
