In a 120-volt circuit, 120 joules of
 
  1) charge move each second, which makes up the current,
  2) energy are given to each unit of charge that makes up the current,
  3) energy are given to each unit of resistance in the circuit,
 
  and if the current is 1 ampere, then
  4) 1 unit of charge per second passes any point in the circuit.
  5) 120 units of charge per second pass any point in the circuit.
  6) the resistance of the circuit is 1 ohm.

Question 2

When two lamps are connected in series to a battery, the electrical resistance that the battery senses is
 
  1) more than the resistance of either lamp,
  2) less than the resistance of either lamp,
 
  And when the same two lamps are connected in parallel to a battery, the electrical resistance that the battery senses is
  3) more than the resistance of either lamp.
  4) less than the resistance of either lamp.
  5) none of these
