It wouldn't be a short because the current is still traveling through bulbs 1 and 2. Back when I was in physics class I would have been able to calculate the current but it's been a year so I'd have to looks it up on google.

that's what I ended up saying. Taking the circuit as a whole, bulbs 1 and 2 would use up the voltage. Adding a chunk of copper to bulb 7 would effectively make it a series circuit, completely cutting out the parallel portion (bulbs 3 thru 7).

You need to know 2 values to calculate the Amperage (current.) Based on the data we have at this point, we can't calculate without assuming certain values, which does not proper work make.
