The excellent circuit simulation that we explored in our lessons is freely available for you to use as part of your independent learning. It was created by the University of Colorado and can be accessed here (or just search for PhET DC simulation). There are, however, a couple of points that you must remember when … Continue reading Circuit Simulation
Voltage and Current
When you first started learning about circuits, either in primary school or in Y7, you should have been told about voltage and current. These two measurements were probably presented as separate ideas but in fact they both relate to one thing; electrical charge. Voltage relates to the amount of energy given to the charge that … Continue reading Voltage and Current
