Question

a constant current flows in the conductor with a magnitude of 1.6 mA. Calculate the charge and number of electrons transferred through the straight cross-section of the conductor in 1 hour.

Answer 1

• Current=1.6mA=1.6×10^{-3}A=0.0016A=I
• Time=1h=3600s=t
• Charge=Q

`\\ \sf\longmapsto I=(Q)/(t)`

`\\ \sf\longmapsto Q=It`

`\\ \sf\longmapsto Q=0.0016(3600)`

`\\ \sf\longmapsto Q=5.76C`
