## What kind of questions are expected from 'Physics' in General Knowledge?

Physics is study of matter. General knowledge papers would include the basic knowledge of physics Energy &work, Unit & Measurement, Heat & Temperature, Speed & Velocity, Quantities & Dimensions, Theories & Formulas, Scalar & Vector Quantities, Inventions & Discoveries, and more.Read general knowledge books and Primary, secondary standard books of physics to gain knowledge topics like ‘Physics’. Also answer more sample questions of General knowledge for better preparation

APPSC (group1, group2), TNPSC (Group1, Grorup2), SSC –CPO- SI, ASI, Indian Navy Artificer Apprentice exam, Government exams (like Civil services, Groups placement tests and more would be some of the career, competitive and entrance exams that include ‘Physics’ in General knowledge papers. General Knowledge is important for students from primary and secondary standards who are attending several entrance exams, quiz contests and other competitive exams.

We have a large collection of sample questions on ‘Physics’ (General knowledge) that are frequently asked in most of the competitive and entrance exams for your practice and score high.

Two electric bulbs marked 25W – 220V and 100W – 220V are connected in series to a 440Vsupply. Which of the bulbs will fuse?

 A) 25 W B) Both C) 100 W D) Neither

Explanation:

Resistances of both the bulbs are

$R_{1}=\frac{V^{2}}{P_{1}}=\frac{220^{2}}{25}$

$R_{2}=\frac{V^{2}}{P_{2}}=\frac{220^{2}}{100}$

Hence  $R_{1}>&space;R_{2}$

When connected in series, the voltages divide in them in the ratio of their resistances. The voltage of 440 V devides in such a way that voltage across 25 w bulb will be more than 220 V. Hence 25 w bulb will fuse.
