Concept explainers

In classical mechanics, kinematics deals with the motion of a particle. It deals only with the position, velocity, acceleration, and displacement of a particle. It has no concern about the source of motion.

Linear Displacement

The term "displacement" refers to when something shifts away from its original "location," and "linear" refers to a straight line. As a result, “Linear Displacement” can be described as the movement of an object in a straight line along a single axis, fo…

220 volts is supplied across 1200 winding of the primary coil of the autotransformer.If 1650 windings are tapped, what voltage will be supplied to the primary coil of thehigh-voltage transformer?2. A kVp meter reads 86 kVp and the turns ratio of the high-voltage step-up transformeris 1200. What is the true voltage across the meter?3. The supply voltage from the autotransformer to the filament transformer is 60 volts. If theturns ratio of the filament transformer is 1/12, what is the filament voltage?4. If the current in the primary side of the filament transformer in question 3 were 0.5 A,what would be the filament current?5. The supply to a high-voltage step-up transformer with a turns ratio of 550 is 190 volts.What is the voltage across the x-ray tube?

220 V is supplied to 800 primary turns of an autotransformer. What will the outputvoltage be across 200 secondary turns? 2. A filament transformer has a turns ratio of 1:20. What current must be supplied to theprimary windings if 5 A is required by the filament? 3. The filament transformer in the previous question is supplied with 150 V to theprimary side. What is the secondary voltage? 4. 440 V is supplied to 1000 primary turns of an autotransformer. If the desired outputvoltage is 100 V how many secondary turns must be tapped?
