Answer:
I=1.6x10-19A
Explanation:
Given Info: Electron in its lowest energy
state moves with the velocity
2.19x 10" m. s in a circular orbit of
radius 5.29 x 10" m, Electron in its lowest
energy state moves with the velocity
2.19 x 10 m-s" in a circular orbit of
radius 5.29 x 10- m.
Explanation:
Formula to calculate the time period of
electron is,
T:
2TT
21
Tis the time period of electron,
ris the radius of circular orbit,
vis the velocity of electron,
Substitute 3.14 for T, 5.29 x 10- m for r
and 2.19x 10 m s for v in the above
equation to find T.
T23.14) (5.29 x 10-1 m)
T-
2.19x10 ms
= 1
Let the current be:
I
=
d
Q
d
t
Where Q is the charge.
If rate of flow of charge is not constant then the current at any instant is given by the differential limit: I = dQ/dt.
If a charge Q flows through the circuit for time t, then
I = Q/t.
Charge of hydrogen atom q = 1.6x10–19C
T = 1
Therefore,
I = 1.6 x 10-19C/1
I=1.6x10-19A
