The Total solution for NCERT class 6-12
If a current of 0.5 ampere flowsthrough a metallic wire for 2 hours, then how many electrons would flow throughthe wire?
I = 0.5 A
t = 2 hours = 2 × 60 × 60 s = 7200 s
Thus, Q = It
= 0.5 A ×7200 s
= 3600 C
Then,
Hence,number of electrons will flowthrough the wire.
