Define one volt.

A bird sitting on a high power electric line is still safe. How?

A $100 \mathrm{\Omega }$ resistor is connected to a $24 \mathrm{V}$ battery. The heat generated per minute will be

A voltmeter has a least count of $0.05$ volt. While doing Ohm's law experiment, a student observed that the pointer of the voltmeter coincides with $15$th divisions. What is the value of observed reading?

The relation between V and I for a conducting wire is -

$4$ students plotted the graph showing the dependence of current $I$ on potential difference $V$ across using their recorded observations. Which of this is the most appropriate graph?

In ohm's law experiment, the physical quantity / quantities which is / are to kept constant while doing experiment is / are:

 List the factors on which the resistance of a conductor depends.
