It details the quipment needed to create a simple circuit, defines the three fundamental values of electricity - volts, ohms and amps - and compares hydraulic and electric circuits. It also looks at how voltage affects a simple circuit, open and closed circuits and direct and alternating currents. The video concludes by explaining magnetism, magnetic fields and electromagnetism\"--Container." . "Introduces basic electrical principles.
