Ohm's Law

The resistance of a cylindrical piece of rubber is _____ than that of a similar piece of copper.
(lesser/greater)

A thick wire has a larger resistance than a thin wire.

A bulb is rated $5.0 \mathrm{V}, 100 \mathrm{mA}$. Calculate its rated power and resistance.

In an experiment, the current flowing through a resistor and the potential difference across it are measured. The values are given below. Show that these values confirm Ohm's law, and find the resistance of the resistor.I

When a 24-V battery is connected to a resistor, the current in it is 0.4 A. What is the resistance of the resistor? What would be the current through it when it is connected to a battery of 6 V?

A $6 \mathrm{V}$ battery is connected across a $5 \mathrm{\Omega }$ resistor. Calculate the current passing through the resistor.

When do you say that the resistance of a wire is $1\Omega$?

Two bulbs have ratings $100 \mathrm{W}$, $220 \mathrm{V}$ and $60 \mathrm{W}$, $220 \mathrm{V}$. Which one has greater resistance?

Consider the units volt, ohm and ampere. One of them is the same as the product of the other two. Which one is this?

What is the shape of the graph between $V$ and I, where $V$ is the potential difference between the ends of a wire and $\mathrm{I}$ is the current in it?
