The answer is:
N32.40


9 A battery has emf 13.2V and internal resistance $24m\Omega$. If the load current is 20.0A, find the terminal voltage o f the battery
The answer is:
12.7V

10 A cirrent flows in a wire of circular cross-section with the free electrons travelling with a mean drift velocity v. If an equal current flows in a wire of the same material but of twice theradius, what is the new mean drift velocity?
The answer is:
v/4
