How many electrons flow through an electric bulb every second, if the current that passes through the bulbs is 1.6 A.
Given: an electric bulb
To find the number of electrons flowing through an electric bulb every second, if the current that passes through the bulbs is 1.6A
Solution:
Use the relation,
I=Qt=net, where n =number of electrons and e = charge on 1 electron and t = time
Using thevallues given in the question we can write,
1.6A=n×e1sec
⟹n=1.61.6×10−19 [∵ charge on 1 electron = 1.6×10−19C]
n=1019
are the required number of electrons.
