The unit of electric charge is the:

## The reasoning Electric charge is a fundamental property of matter, like mass. Just as mass is measured in kilograms, **electric charge is measured in coulombs (C)**. Think of it this way: the coulomb is the "bucket" that holds charge. One coulomb represents approximately 6.24 × 10¹⁸ electrons worth of charge. This unit is named after French physicist Charles-Augustin de Coulomb. The relationship is simple: **Q = It**, where Q (charge in coulombs) = I (current in amperes) × t (time in seconds). So 1 coulomb = 1 ampere flowing for 1 second. ## Why the wrong options tempt you - **Volt** measures electric potential difference (how much "push" the charge has), not the charge itself - **Ampere** measures current (the *flow rate* of charge per second), not the amount of charge - **Ohm** measures resistance (opposition to current flow), totally different concept These all relate to electricity, so they sound plausible if you're rushing! ## Quick takeaway **Coulomb counts the charge; ampere counts how fast it flows; volt counts the push; ohm counts the resistance.** Remember: C for Charge = Coulomb!
