'Current' problem

I don't know what on earth my book states here:

Here's the simulator link (no viruses don't worry!): http://phet.colorado.edu/sims/circuit-construction-kit/circuit-construction-kit-ac_en.jnlp

Please help!

I wouldn't recommend that book - cell current doesn't make sense ....

So is it incorrect, or am I just interpreting them wrong?
It's incorrect.
If you had a 2V cell connected to a 2 ohm resistor the current would be 1 amp assuming no internal resistance.
If you add a second 2V cell in series the current will be 2 amps.
It's basic Ohm's Law.
Get rid of that book.
They have got the series and parallel cell effects the wrong way round for the current.
They may be trying to make a point but they have made a real mess of it.
