An electric wire is connected across a cell of $e.m.f.$ $E$. The current $I$ is measured by an ammeter of resistance $R$. According to Ohm's law,which of the following relations is correct?

$A$ circuit to verify $Ohm's$ law uses an ammeter and a voltmeter. How should they be connected to the resistor?

The charge $q$ (in coulomb) passing through a $10 \, \Omega$ resistor as a function of time $t$ (in second) is given by $q = 3t^2 - 2t + 6$. The potential difference across the ends of the resistor at time $t = 5 \, s$ is: (in $V$)

Select the correct statement.

Of the following graphs,the one that correctly represents the $I-V$ characteristics of an 'Ohmic device' is:

$A$ solenoid is at a potential difference of $60\, V$ and the current flowing through it is $15\, A$. The resistance of the coil will be ............ $\Omega$.
