Question

How much charge will be delivered per minute by a current flow of 750mA​

Answer 1

A current of 750 mA is being carried by a conductor.

• Now, we know that SI unit of current is AMPERE , which is COULOMB/SECOND.

• So, 750 mA means 750 × 10^(-3) Coulomb flowing in 1 second.

Hence, in 1 min (or 60 sec), charge flowing is:

$=( 750 \times {10}^{ - 3} ) \times 60$

$=45000\times {10}^{ - 3}$

$=45 \: Coulomb$

• So, current flowing is 45 Coulombs in 1 minute.

Final answer is :

Current = 45 C/min ✔️
