Electricity: Circuits and their Components
A glowing torch hides a complete path for electric current, and this chapter of the NCERT Curiosity textbook for Class 7 traces it. It introduces cells, bulbs, wires, and switches as parts of a circuit, shows how to draw and assemble open and closed circuits, and explains conductors that let current pass and insulators that block it. Safe activities test which materials conduct, what happens when circuits break, and why switches matter, ending with rules for handling electrical things without risk.
