1.	How many electrons pass through a conductor in 0.2s if the current passing through it is 0.5A?
Answer» A n s w e r :Charge = current * timecharge = 0.50.2charge = 0.1 coulumbwe have q = n e0.1 = n ( 1.60210^-19 )n = 0.1 / 1.60210^-19By dividing it we get the followingn = 0.062410^19n =6.24*10^17 I=0.5At=0.2sQ=t×I=0.2×0.5=0.10sQ=n×en=q/e=0.1/1.6×10-¹⁹ =6.25×10¹⁷
