Question

Calculate the resistivity in ohm meter of 5m wire whose cross sectional area is 10×10^-3m^2 and resistance is 1 ohm.

Answer 1

Answer:

question. Answer: To obtain a combined resistance of 9 ohms, three resistors each of resistance 6 ohm should be connected in a parallel circuit and one in series. In a parallel circuit, the equivalent resistance of all the resistors connected is equal to the reciprocal value of the sum of the individual resistances.
