Class 12 Chemistry - Chapter Electrochemistry NCERT Solutions | If a current of 0.5 ampere flows through
If a current of 0.5 ampere flows through a metallic wire for 2 hours, then how many electrons would flow through the wire?
I = 0.5 A
t = 2 hours = 2 × 60 × 60 s = 7200 s
Thus, Q = It
= 0.5 A × 7200 s
= 3600 C
We know that 96487C = 6.023 X 1023 number of electrons.
Then,
Hence, 2.25 X 1022number of electrons will flow through the wire.
