National University of Sciences and Technology (NUST) is ranked among top engineering universities of Pakistan. NUST was established in 1991, they have many campuses in different cities but their main campus is in Islamabad. NUST was established with a goal of providing quality education to its students and to create better carrier opportunities for them so that they can succeed in their lives. Nust mainly focus on quality education that’s why their fee is quite high but they facilitate poor and needy students through need base scholarship. NUST NET registration is open now and entry test will start from 28th Dec 2018. NUST has earned his status in a very short period of time through their dedication and hard work.

SAMPLE QUESTIONS
TOPIC
Alternating Current
QUESTION
A DC battery can pass current continuously through?
i. Resistor
ii. Capacitor
iii. Inductor
OPTIONS
- I only
- I and II only
- I and III only
- I, II and III
CORRECT OPTION
I and III only
EXPLANATION
DC current cannot flow through a capacitor continuously because of the presence of an insulating medium between the plates of the capacitor.
TOPIC:
Electronics
QUESTION:
Current flowing between two input terminals of operational amplifier is?
OPTIONS:
- Zero
- In the range of milli amperes
- In the range of amperes
- None of the above
CORRECT ANSWER:
Zero
EXPLANATION:
Input resistance of operational amplifiers is very high in the range of mega ohms. Therefore, practically no current flow between the two input terminals.
TOPIC: PHYSICS OF SOLIDS
QUESTION
Which of the following statements is the most appropriate about super conductor’s special conducting property?
OPTIONS
- Zero resistance below critical temperature
- Zero resistance above critical temperature
- Zero resistance at 0 K (Absolute zero)
- Zero resistance at room temperature
CORRECT ANSWER
Zero resistance below critical temperature
EXPLANATION
Super conductors have zero resistance below critical temperature. Critical temperature vary for different type of super conductors. Although super conductors have zero resistance at 0k but need to identify most appropriate statement. So C is not a correct choice for this question.
