Today in metal tech me learned about Electricity, We learned what it is, how it works and how many volts things have. We learned about the different ways energy is made. These two ways are chemical and magnetical. We used maths and science in our deduction of electricity. We also learnt that cars have 12.7 volts, AA batteries have 1.5 volts and sockets in the wall have 220 - 240 volts.
