Q1

Electrons drift with speed \({\mathrm{v}}_{\mathrm{d}}\) in a conductor with potential difference V across its ends. If V is reduced to \(\left(\frac{\mathrm{V}}{2}\right)\), their drift speed will become :

a

\(\frac{{\mathrm{v}}_{\mathrm{d}}}{2}\)

b

\({\mathrm{v}}_{\mathrm{d}}\)

c

\(2{v}_{d}\)

d

\(4{v}_{d}\)
