A 8 V flashlight battery has an internal resistance of 1.7 Ω when new, and 8 Ω when old. Imagine this is a resistor in series with the battery mounted INSIDE the battery itself, which describes the chemical degradation of the battery with age. Calculate the voltage across a 14 Ω lamp (the load) when the battery is new. Express the answer with one decimal place.
