    Simply put: Garden hose filled with water or electrons aka volts.The pressure that pushes the water down the hose is air aka amps. The resistance is If you bend the hose an slow the flow of water without dropping the pressure aka amps. Watts is the amount of force the water pushes against your hand at the other end of the hose away from the source. Here is a simple way to find out how many watts anything in your house use. Look on the back or bottom of a radio it will say something like 120 volts 2 amps multiply 120 x 2 = 240 watts. Lets say same radio 120 volts at 240 watts Divide 240 by 120 = 2 amps.I hope this helps you out.

    to add to Denis' answer:

    P

    -----

    I E

    Power in watts = Current in amps, times Volts

    i.e. 3 Amps * 12 Volts = 36 Watts

    (and of course, P divided by I = E (electromotive force i.e. Volts)

    (and P (power in watts) divided by E (volts) = I (amps)

    too much. I'd suggest looking each term up in wikipedia. Each item is good for many paragraphs.

    A quick summary:

    volts is a measurement of voltage, electric potential.

    amps is a measurement of electric current, a flow of electrons through a wire or device.

    watts is a measurement of power, electric or otherwise. For electric power, watts = voltage x current.

    resistance in electricity is the ratio of voltage to current, and is measured in ohms.

    Ohm's law

    V=IR

    The voltage (units are volts) across a resistor (with resistance R in ohms) is the product of the current (in amperes) through the resistor and the resistance.

    The power, units in watts, through a resistor is the product of voltage across the resistor and the current through it.

    P=VI=(IR)I=I^2R
