Q. 3
The electric curr
Answer :
6.0×10-4C
Given,
The electric current in the tube= 2.0 μA
Time for which charge transfer is to be calculated= 5 min=300s
Formula used
The amount of charge, q, transferred in t seconds, with a current I is
Solution,
The discharge tube carries a current of 2.0 μA. So the charge transferred across the cross-section in 300s, by the above relation, is
So the charge transferred across the cross-section is 6.0×10-4C
