Verified Answer
Which of the following does the electrical resistance not depend on?a)...
  • Resistance is the obstruction experienced by the flow of electrons through a conductor. It is the ratio of applied potential difference (V) to the current (I) flowing through the conductor but is independent of the values of I and V.
  • Resistance depends on the nature of the conductor. The more the impurities, the more will be the resistance and the poorer is the conductor.
  • Resistance is also affected by physical conditions. Example: with the increase in temperature, the resistance increases in case of conductors.
  • Also, resistance is affected by the dimensions of the conductor. It is directly proportional to the length of the conductor and inversely proportional to its area of cross-section (R= r l/A)
