No. When the switch is open, off position, no current flows. The light needs current to operate.

What kind of energy does a lamp use?
light and heat are given off as a result of converting the input energy which I would guess is electrical energy or in the case of gas or oil it is chemical energy
How does electricity flow around a series circuit?
Imagine a series circuit consisting of a battery, a wire from its negative terminal to a lamp, and another wire from its positive terminal to the lamp. The electricity would flow from the battery's negative terminal to the lamp and then back to the positive terminal of the battery: it's always negative to positive. Scientists were not aware of this until long after electricity discovered. They thought electricity flows from positive to negative and this was accepted for a long time. When someone asks you to use conventional current, it means assume the current flows from positive to negative, which is the opposite of what happens in reality. The negative terminal (the technical name for this is cathode) of an electrical energy supply, such as a battery, releases electrons with energy in them. These electrons drift to the appliance (i.e. the lamp in this case). The lamp then uses the energy in the electrons to produce light and heat before letting the electrons out on the other side. These electrons have little or no energy but they would drift back to the battery to regain energy and the cycle continues until the battery is depleted of energy. The electrons leave the lamp at the speed at which they enter the lamp.
When did James watt invent the light bulb?
He didn't. Michael Faraday invented the carbon arc lamp for outdoor use creating light from electricity. Thomas Alva Edison perfected the filament light bulb making it practical for indoor use.
Which was the first thing to electricity?
your question makes no sense, to USE electricity? GENERATE electricity? I think to use.
What did people first use for electricity?
they didn't use electricity they used other things
Does a lamp in off position use electricity?
no
Does a lamp use electricity when it is turned off?
A standard lamp will not use any electricity when it is off.
Does a lamp use electricity when it is off?
No.
Does a lamp use electricity when turned off?
No, it should not use any electricity when off. If it is, you have a short or a ground.
Does a off lamp use electricity?
If it is plugged in, it uses 15% of the electricity it would normally use if it were on. Always unplug your appliances.
Why would switching some street lights save electricity?
Because a lit lamp use energy. Switch it off and you save energy.
What item that continues to use electricity even though its switch may be in the off position?
If a device is switched off at the wall, then that is equivalent of being unplugged and it will not use electricity. However any device with a transformer in it that is switched off at the device (not the wall) will continue to use electricity. Televisions etc are like this, so are mobile phone chargers.
Do heat lamp bulbs use less than regular bulbs?
No, they use more electricity.
How much electricity does a lamp use without a bulb?
None, unless there's a radio or someting else built into the lamp base.
Does a sailor use a gas lamp?
Because sometimes the boat doesn't have electricity to power it.
What happens to electricity when you turn on an elactric lamp?
you use up energy and it is turned into heat
How do you consume electricity?
Electricicty is consumed when hooked to something which turns electricity into something else. A lamp turns electricity into light, and use something up in the process. A fridge use electricity to cool its insides, and use some of it up. A fan use electricity to move air around, and some of it is used up.
