We are glad to be able to inform you that we will be able to provide you with 85,000 motors in November, as in our agreement. The breakdown of the main machinery in our plant has been repaired. We are sorry that we have caused you so much trouble by sending only half the agreed number of motors for this month. At your request we are submitting a semiannual progress report for the Petrochemical Department. Since there have been extensive job restructing and maintenance preparation for the new 5th Shift, a report on the status of the department, though routine, is especially important now.
Electrical current is really the movement of electrons through a conductor.
This movement causes heat. Electrons move easily through some materials, and cause very little heat. Such materials are called good conductors. However, when electrons pass through a poor conductor they meet more resistance. The more resistance the electrons meet, the more heat they will build up.
