It is required to design a zener shunt regulator to provide a regulated voltage of about 10 v. the available 10-v, 1-w zener of type 1n4740 is specified to have a 10-v drop at a test current of 25 ma. at this current, its r z is 7 . the raw supply, v s , available has a nominal value of 20 v but can vary by as much as ±25%. the regulator is required to supply a load current of 0 ma to 20 ma. design for a minimum zener current of 5 ma.

The coulomb's law explains which of the following? select all the force between two charged objects is inversely proportional to the charge on each object. the force between two charged objects is directly proportional to the charge on each object. the force between two charged objects is directly proportional to the distance separating them. the force between two charged objects is inversely proportional to the square of the distance separat coulomb's law is similar to newton's 2nd law. if the force between two objects is f and the charge on both objects is doubled, the new force between the would now be 2f. if the force between two objects is 2f and the distance separating them is doubled, the new force between the objects would now o the be zf.
