Fair enough  
  
* Watts - energy is measured in joules (J), and must be transferred from one place to another to get many things to work (whether that be in an electrical device or in the human body).  1 watt (W) is a rate of energy transfer of 1 joule per second (J s^-1).
* Amps - electrical charge is measured in coulombs (C), and the act of moving electrical charge from one place to another is known as an electrical current.  1 ampere (A) is a rate of transfer of electrical charge of 1 coulomb per second (C s^-1).
* Ohms - it is easier to move a charge through some materials than it is to move that charge through others.  The more difficult it is to move a charge through a material, the higher its resistance is said to be.  Resistance is measured in ohms (Ω).  It is not fixed, but instead may change based on temperature, length or cross-sectional area of a wire.
* Volts - there is a more complicated description involving electrical potential, but voltage is essentially the energy being supplied per coulomb, that is being used to push the charge around the circuit, and is measured in volts (V).

If you keep the voltage the same, but run the current through a material with double the resistance, then you end up with half the current.  This is more formally stated as Ohm's Law; V=iR (voltage = current * resistance).  But it's not actually a fundamental law of physics - it's just something that has been observed in normal conditions for most metals.
