Current and Charge
The movement of charged particles in a conductor.
1. Electric Current and the Amp
Why does electric current have the symbol 'I' and is it just the flow of electrons? Watch this short video to find out a bit more.
2. Charge and the Coulomb
You can try this simple experiment at home, with an energy saving light bulb and a balloon. I also explain a bit more about the property of electric charge and why is has the symbol 'Q'.
3. Kirchhoff's First Law
Kirchhoff's 1st Law states that at any point in an electrical circuit, the sum of currents into that point is equal to the sum of currents out. Electrical charge is conserved.
