The two poles of a dynamo are connected by an iron wire that is $1 \text{ km}$ long and has a diameter of $1.2 \text{ mm}$, and it is found that a current of $12 \text{ amperes}$ flows through this wire. How many watts is the machine's power output? What is the voltage between the poles, and how many horsepower would a gas engine need to drive the dynamo if the efficiency of the dynamo is $0.85$? The resistance of an iron wire that is $1 \text{ m}$ long and has a cross-sectional area of $1 \text{ mm}^2$ is $\frac{1}{12}$ ohms.
