MCQ
Voltage in the secondary coil of a transformer does not depend upon.
  • A
    Voltage in the primary coil
  • B
    Ratio of number of turns in the two coils
  • Frequency of the source
  • D
    Both $(a)$ and $(b)$

Answer

Correct option: C.
Frequency of the source
c
(c) The voltage in primary and secondary coil is related as:

$\Rightarrow \frac{V_{S}}{V_{P}}=\frac{\text {no. of turns in secondary coil }\left(N_{s}\right)}{\text { no. of turns in primary coil }\left(N_{p}\right)}$

Clearly, voltage in secondary coil depends on voltage in primary coil and number of turns in primary and secondary coil. It is independent of frequency of the source.

A source of potential difference $V$ is connected to the combination of two identical capacitors as shown in the figure. When key ' $K$ ' is closed, the total energy stored across the combination is $E _{1}$. Now key ' $K$ ' is opened and dielectric of dielectric constant 5 is introduced between the plates of the capacitors. The total energy stored across the combination is now $E _{2}$. The ratio $E _{1} / E _{2}$ will be :
