Assume you have a power supply using a bridge rectifier. the output of the supply should be 13.8 v with a maximum output current of 50 a. if we assume the voltage regulator in series with the positive output leg requires a minimum of 1.2 v, the input voltage at the regulator has a minimum value of 15 v. (a) draw the circuit. (b) determine the value of c (filter capacitor after rectifier and before regulator) that produces a maximum voltage ripple at the input to the regulator of 5v. (c) determine the rms voltage of the secondary of the transformer.

Imagine an isolated positive point charge q (many times larger than the charge on a single proton). there is a charged particle a (whose charge is much smaller than charge q) at a distance from the point charge q. on which of the following quantities does the magnitude of the electric field created by charge q at particle a's position depend? check all that apply.the type of the charge on the charged particle athe relative orientation between q and a (while the distance between q and a is fixed)the specific location of the charged particle a (while the distance between q and a is fixed)the amount of the charge on the point charge qthe specific location of the point charge q (while the distance between q and a is fixed)the distance between the point charge q and the charged particle athe amount of the charge on the charged particle a

Atrain is traveling at 30.0 m/s relative to the ground in still air. the frequency of the note emitted by the train whistle is 262 hz. the speed of sound in air should be taken as 344 m/s. what frequency (f approach) is heard by a passenger on a train moving at a speed of 18.0 m/s relative to the ground in a direction opposite to the first train and approaching it? what frequency (f recede) is heard by a passenger on a train moving at a speed of 18.0 m/s relative to the ground in a direction opposite to the first train and receding from it?
