Question

11 4. An electron moves in a circle of radius 0-15 m with a constant speed of 3-6 x 106 m sl. What electric current does this correspond to ? [Ans. 6-1 x 10-13 A)​

Answer 1

Explanation:

Using the relation

i=tq=timeperiodelectroniccharge=te

Hence, t=v2πr

So, I=2π/ve

=2πveV

=2×314×1.0×10−2(1.6×10−19)(4×106)

=1×10−11Ω
