(B) The electric current $i$ is defined as the rate of flow of charge,given by $i = \frac{q}{T}$.Since the frequency $
u = \frac{1}{T}$,we can write the current as $i = q 	imes 
u$.Given:Charge of an electron $q = 1.6 	imes 10^{-19} \ C$Frequency $
u = 5 	imes 10^{15} \ Hz$Substituting the values:$i = (1.6 	imes 10^{-19} \ C) 	imes (5 	imes 10^{15} \ Hz)$$i = 8.0 	imes 10^{-4} \ A$To convert the current into $mA$ (milliampere),we multiply by $10^3$:$i = 8.0 	imes 10^{-4} 	imes 10^3 \ mA = 0.8 \ mA$.

If an electron revolves in a circular path of radius $0.5 \times 10^{-10} \ m$ at a frequency of $5 \times 10^{15} \ Hz$,the electric current in the circle is .................. $mA$. (Charge of an electron $= 1.6 \times 10^{-19} \ C$)
