Question 8(i)(a) Draw a schematic diagram of main circuit.(b)	Define conductivity.(c) Of the three connecting wires in a household circuit, which two of the three wires are at the same potential?

Accepted Answer

(a) Schematic diagram of main circuit is shown below:

Draw a schematic diagram of main circuit. Physics Sample Paper Solved ICSE Class 10.

(b) The reciprocal of specific resistance is known as conductivity. It is represented by symbol σ

σ = $\dfrac{1}{ρ}$

Its SI unit is ohm^-1metre^-1 or siemens metre ^-1.

(c) Neutral and earth are at the same potentials.
