Q:

Brightness of bulb depends on voltage or current?

A) Current B) Voltage
C) Both A & B D) None
 
Answer & Explanation Answer: C) Both A & B

Explanation:

Brightness of bulb depends on both voltage and current. The brightness depends on power.

Since we know that  Power (P) = Voltage x Current = V I

So whether you increase the current or the voltage the brightness will increase.

 

Example Illustration:

 If you connect a long bulb and a round bulb in series, the long bulb glows but the round bulb does not. Both of them have the same current flowing through them (they are in series) but the long bulb has a greater voltage across it because it has more resistance (even though V= IR is not obeyed exactly, voltage drop does depend on the resistance). If you connect a round bulb and a long bulb in parallel, however, it is the round bulb that is brighter because now the voltage across both bulbs is the same but the current is larger through the round bulb (smaller resistance).

 

Hence, the brightness of a bulb depends on power i.e, both voltage and current.

Q:

A sum of money becomes 7/6 of itself in 3 years at a certain rate of simple interst. The rate per annum 

A) 5% B) 5.5%
C) 6% D) 6.5%
 
Answer & Explanation Answer: B) 5.5%

Explanation:

sum = x. amount =7x/6.

S.I. =(7x/6 – x) = x/6 ; time = 3 years

Rate =[ (100 * x) / (x * 6 * 3)]% = 5.5%

Q:

Read the passage carefully and choose the best answer to each question out of the four alternatives.

 


Many plays and films have depicted the life story of Gautama Buddha, but what made the musical play The Way Across unique was its regional focus. Directed by G. Kumara Swamy, the play adapted from the book Telangana lo Buddhism focused on the enlightenment of a cursed Brahmin Bawari and his 16 curious disciples willing to understand the deeper truths of birth, death, rebirth and brotherhood.

 

From the impressive use of projector visuals, music and shadow-play, there was every effort to lend authenticity to the theme. Despite the play's focus on Telangana, the native essence was compromised, due to the English rendition (done for a wider reach). The lines appeared jaded with literal translations. The honest performances from the crew impacted only on a surface-level. Kiran Kumar's Bawari act and Krishna Chaitanya Joshi as Pingiya (said to have propagated Buddhism from Telangana to several regions across South India) grab your attention.

 

What was unique about the play, 'The Way Across'?

A) Story line B) Regional focus
C) It was a musical D) It was in English
 
Answer & Explanation Answer: B) Regional focus
