Just got the first 16 of my new series of A level physics simulations up and running. The idea is to bring to life every A level physics equation with a simple simulation. Check them out, and let me know what you want me to build next electricityexplained.com/a-level-sims

Radioactive decay simulation - I've spent all of half-term coding this, and I'm quite proud of it! 😊 It makes the link between radioactivity and half-life that you rarely see, and contradicts the misconception that nuclei disappear when they decay. electricityexplained.com/radioactive-de…


Try out my Circuit Surprises Quiz. It's really aimed at identifying student misconceptions with simple electric circuits, but I definitely had most of them when I started teaching! electricityexplained.com/circuit-surpri…


Very excited to be the guest on the View from the Lab podcast hosted by the effervescent Andy Woods at Pearson, talking about #ElectricityExplained on.soundcloud.com/R5oA7


Can't believe the energy and enthusiasm from the science department at Holly Lodge High School for my CPD on Teaching Electricity last week. Thank you so much to HoS Leanne Taylor-Lloyd, and Thomas Millichamp for his enthusiasm for electricityexplained.com


Teaching Radioactivity this term? Let me know which videos you want me to create quizzes and standalone visuals for electricityexplained.com/radioactivity-…


The fact that there is a discussion about this shows why the water circuit analogy for electric circuits isn't really that useful.

How do pressure and velocity change at points 2 and 3?

Is my rule of thumb right - you always need at least one more lead when you insert an ammeter? 🤔 electricityexplained.com/cr-vis-inserti…

Conducting path through a bulb. Not sure how good I am at convincing people that the green blob just traces the path - it's not the current itself. electricityexplained.com/cr-vis-conduct…

Same time ignoring air resistance. Basketball pulled harder but harder to accelerate. Baseball easier to accelerate but not pulled as hard. Gravitational mass and inertial mass just happen to be exactly equal (in a Newtonian world).

Amazing what Google Books has. Here's an 1891 English translation of Georg Ohm's seminal 1827 work The Galvanic Circuit Investigated Mathematically. No mention of resistance. In English books.google.com/books/about/Th… and the original German books.google.com/books/about/Di…

Fascinating that the drift speed of electrons in a filament doesn't depend on the thickness, only the p.d. The thicker filament means a bigger current, but this bigger current is made up of more electrons moving side by side at the same speed. electricityexplained.com


The difference between small and big AC currents using bicycle wheels. The current still changes direction 50 times per second, but the size of the oscillation is bigger.electricityexplained.com/cr-vis-small-a…


The number of free electrons you need to make one coulomb of charge is the same as the number of grains of sand on a beach 500 km long. And they all fit in to to just 1 mm of wire!
