Question: A rectifier circuit has load resistance R. It uses a capacitance filter having capacitance C. For low ripple in the output
[A].

RC should be 1

[B].

RC should be low

[C].

RC should be high

[D].

Question: A coil of resistance R and inductance L is connected in series with 5 μF capacitor. The source frequency is equal to resonance frequency and circuit current is 0.5 A. Another 5 F capacitor is connected in parallel with the above capacitor. The circuit current will be
[A].

0.5 A

[B].

more than 0.5 A

[C].

less than 0.5 A

[D].

0.5 A or less

Answer: Option C

Explanation:

Since C increases, the circuit will not be in resonance. Therefore, current decreases (In series resonant circuit current is maximum at resonance).

For too long, school cafeterias, in an effort to provide food they thought would be appetizing to young people, mimicked fast-food restaurants, serving items such as burgers and fries, pizza, hot dogs, and fried chicken. School districts nationwide are now addressing this trend by incorporating some simple and inexpensive options that will make cafeteria lunches healthier while still appealing to students. This paragraph best supports the statement that

Question: For too long, school cafeterias, in an effort to provide food they thought would be appetizing to young people, mimicked fast-food restaurants, serving items such as burgers and fries, pizza, hot dogs, and fried chicken. School districts nationwide are now addressing this trend by incorporating some simple and inexpensive options that will make cafeteria lunches healthier while still appealing to students.
This paragraph best supports the statement that
[A].

school cafeterias have always emphasized nutritional guidelines over any other considerations.

[B].

young people would rather eat in a school cafeteria than a local fast-food restaurant.

[C].

school lunch menus are becoming healthier due to major new initiatives on the part of school districts.

[D].

it is possible to make school lunches both healthier and appealing without spending a great deal of money and undertaking a radical transformation.

Answer: Option D

Explanation:

The final sentence of the paragraph supports choice d. The other choices are not supported by the passage. Choice c may seem correct at first, but the paragraph states that the new initiatives are simple and inexpensive, not major. Choice e might seem to represent a truth, but vegetarian options are not discussed in this paragraph.
