Paheli wanted to glow a torch bulb using a cell. She could not get connecting wires, instead, she got two strips of aluminium foil. Will she succeed? Explain, how?
Yes. Paheli can use aluminium foil instead of connecting wires as aluminium is a good conductor of electricity. Conductors are materials which allow electric current to pass through it.
Paheli and her friends were decorating the class bulletin board. She dropped the box of stainless steel pins by mistake. She tried to collect the pins using a magnet. She could not succeed. What could be the reason for this?
Paheli connected two bulbs to a cell as shown in the figure. She found that filament of the bulb B is broken. Will the bulb A glow in this circuit? Give reason.
