While cruising down University Boulevard you are stopped by a cop who states that you ran a red traffic light. Because you don't want to pay the stiff fine, you are attempting a physics defense. You claim that due to the relativistic Doppler effect, the red color of the light λ=616 nm appeared green '=531 nm to you. The cop makes a quick calculation of his own and rejects your defense. How fast, in terms of your speed u divided by the speed of light in vacuum c, would you have to drive to justify your claim? Note that the speed u is taken to be a positive quantity. U 4.0 C

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?

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.
