Aim To trace the path of a ray of light passing through a rectangular glass slab for different angles of incidence. Measure the angle of incidence, angle of refraction, angle of emergence and interpret the result. Materials Required Drawing board Drawing pins Three plane sheets of white paper A rectangular glass slab Geometry instruments Sharp […]
Aim To determine the equivalent resistance of two resistors when connected in parallel. Materials Required Two resistors A battery eliminator Ammeter Plug key Connecting wires A piece of sandpaper Voltmeter Rheostat Theory When two or more resistors are connected together between two points then they are said to be connected in parallel. In parallel combination, […]
