Calculate electric charge (q) using the formula q = I × t in real-time
The electric charge (q) carried by a current (I) over a period of time (t) is calculated using the formula:
Where:
• q = Electric charge in Coulombs (C)
• I = Current in Amperes (A)
• t = Time in seconds (s)
Welcome to our free online Electric Charge Calculator! This powerful tool allows you to instantly calculate electric charge using the fundamental formula q = I × t. Whether you're a student, engineer, or electronics enthusiast, this calculator provides quick and accurate results.
Our calculator works in real-time, updating results as you type. Simply enter the current in amperes (A) and the time in seconds (s), and the calculator will immediately display the electric charge in coulombs (C).
This tool is completely free to use with no registration required. It works directly in your browser without sending data to any servers, ensuring your privacy and security. The responsive design works perfectly on mobile devices, tablets, and desktops.
Electric charge is a fundamental property of matter that causes it to experience a force when placed in an electromagnetic field. It's measured in coulombs (C).
This calculator uses standard SI units: current in amperes (A), time in seconds (s), and charge in coulombs (C).
While this calculator focuses on calculating charge, you can easily rearrange the formula: I = q/t for current or t = q/I for time.
This calculator is designed for DC (direct current) applications. For AC circuits, you'll need to consider additional factors like RMS values and power factors.
There are no practical limits to the values you can calculate. The calculator can handle extremely small values (like nanoamperes) to very large values (like kiloamperes).
