Answer 1

Explanation:

When 5 Volt potential difference is applied across a wire off length o I metre the drift speed of the electrons is 2.5 X 10 metre per seconder the electron density in the wire is 8 X 10 per metre cubed the resistivity of the material is close to [2 marks]- a 1.6 into 10 ohm metre b. 1.6 X 10 ohm metre c. 1.6 X 10 ohm metre d 1.6 X 10 ohm metre
