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] = [A1 T1]
- Hence, option 1 is correct.
