Chances are about 50-50 that in any night sky, there is at least one visible comet that has not been discovered. This keeps amateur astronomers busy looking night after night, partly because the discoverer of a comet gets the honor of having it named for him or her. With this high probability of comets being visible in the sky, why aren’t more of them found?

6. 6. There are 1000 turns on the primary side of a transformer and 200 turns on thesecondary side. If 440 V are supplied to the primary winding, what is the voltageinduced in the secondary winding? Is this a step-up or step-down transformer?
7. 80 V are supplied to the primary winding of a transformer that has 50 turns. If thesecondary side has 50,000 turns, what is the voltage induced on the secondary side?Is this a step-up or step-down transformer?
8. There are 50 turns on the primary side of a transformer and 500 turns on thesecondary side. The current through the primary winding is 6 A. What is the turnsratio of this transformer? What is the current, in milliamps, through the secondarywinding?9. The current through the primary winding on a transformer is 5 A. There are 1000turns on the primary winding and 20 turns on the secondary winding. What is theturns ratio of this transformer? What is the current, in amps, through the secondarywinding?
