Question

What is the SI unit of charge?

Answer 1

Step 1: Introduction

1. Electric charge is a property of particles of materials or matter that allows them to experience a force when placed in a magnetic or electric field.
2. Positive charge is carried by Protons.
3. Negative charge is carried by electrons.
4. Like charges repel each other and opposite charges attract each other.
5. Mathematically, it can be expressed as, $Q=I\times t$, where $Q$ is the charge, $I$ represents current, and, $t$ is the time taken.

An illustrative diagram showing the force of attraction between the opposite charges is given below.

Step 3: SI unit of charge

1. Coulomb is the SI unit of charge and is denoted by $\mathrm{C}$.
2. It is a scalar quantity.
