Question

list any two factors on which resistance of a conductor depends. calculate the number of electrons constituting one coulomb of charge.(charge on 1 electrone =1.6×10¯¹9

Answer 1

A. The resistance of a conductor is depends on ----

1. length of the conductor

2. resistivity of the conductor

Answer 2

lenght of wire

and resistivity

Given that

Charge (Q) = 1 C

Electron (e) = 1.6× 10^-19

Number of electron (n) = ?

Q= ne

1 C = n × 1.6×10^-19 C

n = 1/(1.6×10^-19)

n = 6.25 × 10^18 electron
