The resistance of one conducting wire is $10\, \Omega$. If battery of $1.5\, V$ is connected to it, then how much electric current will flow through it?
$15\;m\;A$
$1.5\;m\;A$
$15\;m\;A$
$150\;m\;A$
If the charge on an electron be $1.6 \times 10^{-19} C$, find the approximate number of electrons in $1 C$
Two electric circuits $I$ and $II$ are shown in figure
$(i)$ Which of the two circuits has more resistance ?
$(ii)$ Through which circuit, more current passes ?
$(iii)$ In which circuit, the potential difference across each resistor is equal.
A series circuit has only one conducting path for the electrons that move through it; a paralle circuit has multiple conducting paths.
In Volta's cell, what is the direction of the flow of electrons?
If a $12\, V$ battery is connected to the arrangement of resistances given below, calculate
