Judge the real battery claims

Questions
  1. Statement is true
    Yes
    Statement
    The potential difference across a battery is smaller once it sits in a complete circuit.
  2. Statement is true
    No
    Statement
    The emf of a battery rises as the current drawn by the load rises.
  3. Statement is true
    Yes
    Statement
    A real battery has internal resistance as well as an emf.
  4. Statement is true
    No
    Statement
    Adding more resistance to a circuit increases the current the battery delivers.
  5. Statement is true
    Yes
    Statement
    The terminal potential difference equals the emf only when the current is very small.
  6. Statement is true
    Yes
    Statement
    The gap between emf and terminal potential difference is called the lost volts.
Instructions
Tap true or false for each claim about a real battery with internal resistance.
