I electron has a charge of 1.6 × 10-19 C 1010 electrons would have a charge of q = ne =1.6 × 10-19 × 1010 =1.6 × 10-9 C Thus, in 1 s, charge accumulated =1.6 × 10-9 C So, time taken to accumulate 1 C =(1/1.6 × 10-9)=0.625 × 109 =6.25 × 108 s=173611 h =7233 days =20 yr

I electron has a charge of 1.6×10−19C1010 electrons would have a charge of q= ne =1.6×10−19×1010 =1.6×10−9C Thus, in 1s, charge accumulated =1.6×10−9C So, time taken to accumulate 1C =1.6×10−91​=0.625×109 =6.25×108s=173611h =7233 days =20yr
