The dimensional formula of Charge is

**[ M**^{0}** L**^{0}** T**^{1}** A**^{1}**]**

where **[M]**, **[L],** **[T]**, and **[A]** are the fundamental quantities: **Mass**, **Length**, **Time**, and **Ampere**.

From the above formula, the **dimensions of charge are (0, 0, 1, 1)**.

## How to calculate the dimensional formula of charge?

We can use the mathematical formula of charge to derive its dimensional formula.

```
Charge = Current * time
```

Dimensionally, we use **[A]** to represent current and **[T]** for time.

```
Charge = [A] * [T].
```

Also, it doesn’t have fundamental quantities, mass, and length, so we can use **[M ^{0}]** and

**[L**which means

^{0}]**1**. Now the formula becomes

```
Charge = [M
```^{0}] * [L^{0}] * [T^{1}] * [A^{1}]

Hence, the **dimensional equation of Charge is q = [ M**^{0}** L**^{0}** T**^{1}** A**^{1}**]**.

## Frequently Asked Questions

**1. What is the dimensional formula of Coulomb?**

Coulomb is not a separate physical quantity, instead, it’s the SI unit of charge. Hence, it will have the same dimensional formula as the charge, **[ M ^{0} L^{0} T^{1} A^{1} ]**.

**2. What is the dimensional formula of electric charge?**

Electric charge and charge are the same, so they have the same dimensional formula.

**3. What is the dimensions of q?**

q is the symbol of charge, so the dimensions of **q** are **(0, 0, 1, 1)** in terms of mass, length, time, and ampere.
