List the factors on which the resistance of a conductor in the shape of a wire depends. that will help you delve a bit deeper into the chapters and get a vast understanding of the concepts that are practised in every single one of them. Explain why, the filaments of electric bulbs are made of tungsten. Clearly, their series equivalent resistance $=2+2=4\Omega $ . Question 6 One of the best ways which you can adapt to keep yourself intact and hooked with studies is to keep away from distractions. While the rest of bulbs in parallel circuit will continue to glow without getting disturbed because in parallel combination, current gets additional paths to flow. Question 7. These portions provide an idea about the average velocity obtained by the charged particles, use of resistivity in solving various problems and mobility of electrons helps to pass an electric current. The property of a conductor that prevents current from flowing through it is called resistance.
