Arre, simple project kar sakte ho paper capacitor banake — alag-alag papers (akhbaar, chart, copy) ke dielectric constant compare karoge. Apparatus sirfan multimeter, aluminium foil aur wires chahiye, jo mil jaayega. Humare yahaan bade lab equipment nahi hain, isliye maine apne bete ke saath aise hi ek project kiya tha, uska cost bhi kam tha aur school mei bhi achcha laga.
