Imagine a garden hose.
Turn the water on, and try to keep the water from coming out the end.
The pressure is equivalent to voltage.
The volume of water coming out is equivalent to current.
Resistance is equivalent to the diameter/overall length of the hose.

Actually, it does indeed help a lot. Helps me form that picture in my head that I need to understand things.

Now -
Volt? = voltage
Watt? = volt x current (1 volt x 1 ampere = 1 watt)
Ampere? = current

So, if you have household electricity of 115 volts, and a 500 watt appliance, it is using 500/115 amperes of current, (about 4.3 amps)

It gets more complicated than that, but you can usually just do the math above and get close enough.
