Electric potential as energy per charge
Electric potential as energy per charge
Electric potential is an energy idea. Instead of asking how much force acts on a charge, we ask how much energy is transferred per coulomb.
Step-by-step lessons on Edexcel A Level Physics Electric potential and energy. Each one builds up to exam-style questions. Physics is one of the most mathematically demanding A Levels -- at least 40% of the marks across the three papers require maths skills at Level 2 (GCSE) standard or above, so build calculation and graph-handling fluency alongside the conceptual content from the start.
