Question

Electrical resistance of a wire is

500 ohm Its electrical conductance
will be
i)500 ohm
ii)50 ohm-1
iii) 0:02 ohm
iv)0·002 ohm-1​

Answer 1

Concept:

The following equations express the reciprocal relationship between conductance and resistance: R = 1/G, G = 1/R. The greater the resistance, the lower the conductance, and vice versa.

Given:

The electrical resistance of a wire (R) = 500 ohm

Find:

Calculate the electrical conductance of a wire.

Solution:

We know that the electrical conductance of a wire can be expressed as:

                            Conductance (G) = 1 / Resistance (R)

By substituting the given values in the above expression, we can calculate the conductance of a wire as follows below.

                                                      G = 1 / 500 ohm⁻¹

                                                      G = 0.002 ohm⁻¹

Thus, the electrical conductance of a wire is 0.002 ohm⁻¹.

Hence, the correct option is 0.002 ohm⁻¹.
