Correct Answer  Option 1 : [A
^{1} T
^{1}]
CONCEPT:
Electric Charge
 It is defined as the intrinsic property of certain fundamental particles like electrons, proton, etc, due to which they produce electric and magnetic effects.
 Types of electric charge

Positive charge: A body having a deficiency of electrons.

Negative charge: A body having an excess of electrons.
 Properties of electric charge
 Like charges repel and unlike charges attract each other.
 A charge is a scalar quantity.
 The unit of charge is the coulomb.
⇒ 1 coulomb = charge on 625 × 1016 electrons
EXPLANATION:
As we know, mathematically electric current is written as
\(⇒ Current (I) = \frac{Charge(Q)}{time (t)}\)
The above equation can be written as,
⇒ Charge (Q) = Current (I) × times (t)
 The dimension of electric charge is given as,
⇒ [Q] = [A^{1} T^{1}]
 Hence, option 1 is correct.
