In an atom an electron revolves around the nucleus in a circular orbit

1.	In an atom an electron revolves around the nucleus in a circular orbit at the rate of `6xx10^(15)` revolutions per second. Calculate the equivalent current in milliampere. Take value of electromic charge `= 1.6xx10^(-19)C`.
Answer» Here, `v=6 xx 10^(15) s^(-1)`, `e=1.6 xx10^(-19)C` Equivalent current I=ev `=(1.6 xx 10^(-19))xx6xx10^(15)=9.6xx10^(-4)A` `=9.6 xx10^(-4) xx 10^(3)mA` `=0.96 mA`
