General Studies and Engineering Aptitude flashcards for UPSC ESE Electrical Engineering

24 of 51 cards from the General Studies and Engineering Aptitude deck — real questions with worked answers.

1. In the UPSC ESE pattern, what is the structure and mark distribution of the General Studies and Engineering Aptitude paper (Paper-I)?

   It is a 2-hour objective (MCQ) paper worth 200 marks, common to all engineering disciplines, covering current affairs, reasoning, aptitude, engineering maths, drawing, ethics, materials, design, ICT, energy/environment, project management, and quality/safety.

2. Define 'current events of national and international importance' as tested in competitive exams.

   It refers to significant recent developments in politics, economy, science, sports, awards, summits, and international relations that a candidate must track from reliable news sources over roughly the preceding 12 months.

3. What is the difference between deductive and inductive reasoning?

   Deductive reasoning moves from general premises to a specific, logically certain conclusion; inductive reasoning generalizes from specific observations to a probable (not certain) conclusion.

4. In syllogism (logical reasoning), what does the conclusion 'Some A are B' logically imply about 'Some B are A'?

   It implies that 'Some B are A' is also true, because particular affirmative statements are convertible (conversion is valid for the I-type proposition).

5. What is a 'coding-decoding' problem in analytical reasoning?

   A problem where letters/numbers in a word are replaced by other symbols following a hidden rule (e.g., shifting positions in the alphabet), and the candidate must deduce the rule to encode or decode new terms.

6. Define 'data interpretation' and list its common chart formats.

   Data interpretation is the skill of reading, comparing, and computing from presented data. Common formats: tables, bar charts, line graphs, pie charts, and combination/caselet data sets.

7. In a pie chart, what is the formula relating a category's value to its central angle?

   $$\text{Angle} = \frac{\text{Category value}}{\text{Total}} \times 360^{\circ}$$

8. What is 'data sufficiency' and how are its standard answer options framed?

   Data sufficiency tests whether given statements provide enough information to answer a question. Options typically are: (A) statement 1 alone suffices, (B) statement 2 alone suffices, (C) both together suffice, (D) each alone suffices, (E) both together are insufficient.

9. In numerical analysis, what is the percentage increase formula from value $a$ to value $b$?

   $$\%\text{ increase} = \frac{b - a}{a} \times 100$$

10. State the formula for compound interest with principal $P$, rate $r$ per period, and $n$ periods.

    $$A = P\left(1 + \frac{r}{100}\right)^{n}$$ where $A$ is the final amount.

11. What condition makes a square matrix $A$ invertible (non-singular)?

    $A$ is invertible if and only if $\det(A) \neq 0$, equivalently its rows/columns are linearly independent and it has full rank.

12. Define the rank of a matrix.

    The rank is the maximum number of linearly independent rows (or equivalently columns) of the matrix, equal to the order of its largest non-zero minor.

13. What is the characteristic equation used to find the eigenvalues of a matrix $A$?

    $$\det(A - \lambda I) = 0$$ where $\lambda$ are the eigenvalues and $I$ is the identity matrix.

14. State the Cayley-Hamilton theorem.

    Every square matrix satisfies its own characteristic equation; i.e., substituting the matrix $A$ into its characteristic polynomial yields the zero matrix.

15. For a system $A\vec{x}=\vec{b}$, what does Cramer's rule give for the $i$-th unknown?

    $$x_i = \frac{\det(A_i)}{\det(A)}$$ where $A_i$ is $A$ with its $i$-th column replaced by $\vec{b}$, valid when $\det(A)\neq 0$.

16. State the limit definition of the derivative of $f(x)$.

    $$f'(x) = \lim_{h \to 0} \frac{f(x+h) - f(x)}{h}$$

17. State the product rule and quotient rule of differentiation.

    Product: $(uv)' = u'v + uv'$. Quotient: $\left(\dfrac{u}{v}\right)' = \dfrac{u'v - uv'}{v^{2}}$.

18. What is the Fundamental Theorem of Calculus (evaluation part)?

    $$\int_{a}^{b} f(x)\,dx = F(b) - F(a)$$ where $F$ is an antiderivative of $f$, i.e., $F'(x)=f(x)$.

19. State Taylor's series expansion of $f(x)$ about $x=a$.

    $$f(x) = f(a) + f'(a)(x-a) + \frac{f''(a)}{2!}(x-a)^{2} + \cdots + \frac{f^{(n)}(a)}{n!}(x-a)^{n} + \cdots$$

20. What condition identifies a local maximum of $f(x)$ using the second derivative test?

    At a critical point where $f'(x)=0$, if $f''(x) < 0$ then $x$ is a local maximum; if $f''(x) > 0$ it is a local minimum.

21. Define the order and degree of a differential equation.

    Order is the highest derivative present; degree is the power of that highest-order derivative after the equation is made free of radicals/fractions in derivatives.

22. What is the general solution form of a first-order linear ODE $\frac{dy}{dx} + P(x)y = Q(x)$?

    Using integrating factor $\mu = e^{\int P\,dx}$: $$y\,\mu = \int Q\,\mu\,dx + C$$

23. What is the condition for an equation $M\,dx + N\,dy = 0$ to be exact?

    $$\frac{\partial M}{\partial y} = \frac{\partial N}{\partial x}$$

24. State the Cauchy-Riemann equations for a complex function $f(z)=u(x,y)+iv(x,y)$ to be analytic.

    $$\frac{\partial u}{\partial x} = \frac{\partial v}{\partial y}, \qquad \frac{\partial u}{\partial y} = -\frac{\partial v}{\partial x}$$
