Physics Made Easy: Work, Charge & Potential Difference Explained

Описание: Physics always finds a way to connect directly to our everyday lives, and this problem is a perfect example. The question is simple to state but rich in meaning:

What quantity of charge must be delivered by a battery with a potential difference of 100 V to do 500 J of work?

At first glance, this might look like one of those problems that only advanced students can attempt. But the truth is, it’s built on a very basic idea how energy, charge, and potential difference are related. Whenever you switch on a torchlight, use your phone, or power a fan, the battery inside is constantly doing this same type of “work.” It delivers energy to charges, which then flow to produce light, sound, or motion.

This particular problem asks us to connect three important concepts: work done (energy), potential difference (voltage), and charge (Q). These three quantities are tied together in a simple relationship that students often overlook but is one of the foundations of electricity. By working through this type of question, learners don’t just prepare for exams; they also begin to appreciate how batteries, circuits, and energy transfer actually function.

In this video, I explained the question step-by-step in Pidgin English so it feels real and relatable, especially for students in underdeveloped communities. Too often, physics is presented as abstract and intimidating. But when you explain it in simple language, suddenly it makes sense. Everyone can see that physics is not a monster but simply a way to describe how the world works.

So, as you watch, I encourage you not to just copy answers but to think about the meaning. Share your own attempt in the comments, spread the video to your classmates, and don’t forget to like, save, and follow InstructorAllison for more lessons that make tough science simple and fun.
