    Lightbulb electricity vs. power

    Analysts warning this year's electricity shortfall could be more severe than in 2004, when the country was affected by its worst power shortage in decades because of soaring demand for power as the economy boomed.
    Hi! What is the difference between "electricity" and "power"? Thank you!

    Re: electricity vs. power

    I'll try to help.

    A power shortage causes electricity shortfalls.

    I think that power in this case is the total amount of energy of the country and electricity is what is supplied to houses, industries.

    regards,

    student.

    Re: electricity vs. power

    'electricity' is what actually flows through the lines and cables into our electric appliances.
    'power' is energy that is produced by some mechanical (wind turbines), electrical, or other means that is used to operate a device.
    However, we commonly refer to electrical energy supplied to an area, a building, an appliance, as 'power'.
    So, on electrical products, you will see the switch labelled Power On/Off.
    If the electricity lines come down in a storm, we'd say "the power went off'.
    We could say 'the electricity's off', but that has 5 syllables, and so it's easier for people just to say 'power'.

    When we move into a brand new house, we might say, "I have to get the electricity/power connected/turned on".
    You connect up all the speakers etc to your hi-fi system and then you 'turn on the power' (far less so would you say, 'turn on the electricity'.

    You get an electric shock if you touch a bare wire (not a power shock)
    We refer to electric kettles/jugs for boiling water (not power kettles) to contrast them with the kind of kettle you put on the hot plate of a stove.
    a blanket and an electric blanket
    a fire and an electric fire/a gas fire
    a razor and an electric razor
    a toothbrush and an electric toothbrush

    As you can see, there are times when they are interchangeable, times when they are not, and times when one is used more than the other.

    Re: electricity vs. power

    In physics, electricity is a form of energy (measure in joules) which can be easily converted to others forms of energy such as heat and light, which makes it very convenient to use.

    Power is the rate of doing work (measured in watts) or the rate of expending energy. Electrical appliances have power ratings expressed in watts(W) eg. a light bulb of 40W or 100W.

    However, the practice the two words are used interchangeably.

    Power can come from different sources- steam power, etc.
