• A. Quantity of electricity
• B. Strength of electric current
• C. Power
• D. Energy

Answer 1

The correct option is A

Quantity of electricity

Explanation for correct option:

In case of option A:

Quantity of electricity means net charge flown.

Mathematically, $I=\frac{Q}{t}$

where, $I=current$

$Q=charge$

$t=time$

$Q=I\times t$

$=Ampere-hour$

Explanation for incorrect options:

In case of option B:

1. Unit of the strength of the electric current is $Ampere$.

In case of option C:

1. Unit of power is $joule/second$.

In case of option D:

1. Unit of energy is $joule$.

Hence, option A is the correct answer.
