Q. The speed at which the current travels, in a conductor, is nearly
A) $3 \times 10^{- 4}\ ms^{- 1}$
B) $3 \times 10^{- 5}\ ms^{- 1}$
C) $4 \times 10^{6}\ ms^{- 1}$
D) $3 \times 10^{8}\ ms^{- 1}$
Explanation
(d) The speed at which current travels through the conductors means the speed of electric effect travelling through conductor which is at a speed of light
