Circuit questions

1.  What exactly is voltage, current and resistance?
2.  What is Ohm's law?
3.  Consider a 9-V battery connected to a 6-ohm resistor.  What is the current through the resistor?
4.  Consider 2 batteries (1.5 V each).  They are connected in series to 2 resistors (10 and 30 ohms).  Find the current through each resistor.
5.  In the problem above, what would happen if one of the resistors was removed from the circuit?
