Electrolysis For JAMB-WAEC 2025: How To Find The Charge Passed Through A Solution

How to Calculate the Charge (Coulombs) Passed Through a Solution | JAMB & WAEC 2025 Chemistry Tutorial Welcome to this physics tutorial, where I will explain how to calculate the total charge (in Coulombs) that flows through a solution when a current of 6.5 Amperes is allowed to pass for 1 hour. This type of question is common in JAMB, WAEC, and NECO Physics exams under the topic of Current Electricity and Electrolysis. Many students struggle with it, but I have simplified the explanation in pidgin English so that everyone can understand it easily. By the end of this video, you will learn: ✅ The formula for electric charge ✅ How to apply it to solve problems in WAEC and JAMB ✅ Common mistakes students make and how to avoid them Make sure you watch the video to the end, like, share with your friends, and subscribe for more physics and mathematics tutorials. If you have any questions, drop them in the comments section, and I will be happy to help. Now, let’s dive into the solution to this problem! Understanding the Formula for Charge To calculate the charge (Q) that passes through a solution, we use the formula: Q = It Where: Q = Charge in Coulombs (C) I = Current in Amperes (A) t = Time in seconds (s) This formula is very important in electrolysis and electricity calculations. It tells us how much electric charge has been transferred when a current flows for a certain period. Step-by-Step Solution to the Problem Given Data: Current (I) = 6.5 A Time (t) = 1 hour Since time must be in seconds, we convert: 1 \text{ hour} = 60 \times 60 = 3600 \text{ seconds} Step 1: Apply the Formula Q = It Substituting the values: Q = 6.5 \times 3600 Step 2: Multiply Q = 23400 \text{ Coulombs} So, the total charge passed through the solution is 23,400 C. ✅ Why is This Important in JAMB & WAEC Physics? This formula is useful in: ✔ Electrolysis calculations (e.g., finding the mass of deposited substances) ✔ Current electricity problems ✔ Understanding how electric charge is transferred in circuits ✔ Real-world applications like batteries, capacitors, and electroplating Common Mistakes Students Make in This Topic 🚫 Forgetting to Convert Time to Seconds Always remember that time must be in seconds (s) before applying the formula. 🚫 Using the Wrong Formula Some students mistakenly use Ohm’s Law (V = IR) instead of Q = It. Make sure you use the correct formula for charge. 🚫 Wrong Multiplication Be careful when multiplying values, especially during time conversion. If you are preparing for JAMB, WAEC, or NECO 2025, understanding electric charge, current, and time relationships is very important because: ✅ It frequently appears in JAMB past questions ✅ It is useful in topics like electrolysis, electricity, and circuits ✅ It helps in understanding how electrical devices work Here are tips to help you pass JAMB and WAEC 2025: ✔ Practice Past Questions Regularly ✔ Memorize Important Physics Formulas ✔ Understand the SI Units for Time, Current, and Charge ✔ Watch More Tutorial Videos ✔ Ask Questions If You Don’t Understand Mastering this topic will make Physics calculations easier for you! In this tutorial, we have learned: ✔ The formula for charge (Q = It) ✔ How to calculate charge when given current and time ✔ Why this topic is important for JAMB & WAEC ✔ Common mistakes and how to avoid them I hope this explanation helps you understand electric charge calculations better.
