Probe the nature of like and unlike charges. Improvise bulb holders, battery holders and switches to configure parallel and series circuits. Predict current flow using Ohm's law. Construct galvanometers, variable resistors, fuses, electroscopes, wet cells, storage cells and ammeters. Split water and recombine the gases in a safe mini-explosion!
