Two bulbs $X$ and $Y$ have the same voltage rating and their power ratings are $40 \ W$ and $60 \ W$ respectively. They are connected in series to a $300 \ V$ battery as shown in the figure. Then:

  • A
    $X$ will glow brighter.
  • B
    The resistance of $Y$ is greater than that of $X$.
  • C
    The heat produced in $Y$ is greater than that in $X$.
  • D
    The potential difference across $X$ is less than that across $Y$.

$A$ current of $2.0 \, A$ passes through a cell of $e.m.f.$ $1.5 \, V$ having an internal resistance of $0.15 \, \Omega$. The potential difference measured,in $volts$,across the terminals of the cell will be:

$A$ resistor ${R_1}$ dissipates the power $P$ when connected to a certain generator. If the resistor ${R_2}$ is put in series with ${R_1}$,the power dissipated by ${R_1}$

The circuit diagram shown consists of an infinite number of elements (each element has two resistors $R_1$ and $R_2$). The resistance of the resistors in each subsequent element differs by a factor of $K = 1/2$ from the resistance of the resistors in the previous elements. The equivalent resistance between $A$ and $B$ shown in the figure is:

In the given circuit diagram,the galvanometer reading is zero. If the internal resistance of the cell is neglected,then the value of $X$ is ......... $\Omega$.
