Question

An electric current of 12 ampere flows through a conductor in 15 seconds. Find the amount of charge that flows through the conductor.

• A. $180\text{coulomb}$
• B. $150\text{coulomb}$
• C. $100\text{coulomb}$
• D. $2000\text{coulomb}$

Answer 1

The correct option is A $180\text{coulomb}$

Use formula of current
$I=Q/T=12=Q/15=Q=15\times 12=180\text{coulomb}$
