The true method of knowledge is experiment.
The students of class VI BF Primary and Middle School designed circuits for better understanding of flow of charges in a closed circuit.
From this activity the students learnt, when a circuit is complete, or closed, electrons can flow from one end of a battery all the way around, through the wires, to the other end of the battery. Along its way, it carries electrons to electrical objects that are connected to it – like the light bulb – and make them work!
