Use of multimeter Aim Use of multimeter to see the unidirectional flow of current in case of a diode and an LED and check whether a given electronic component (e.g., diode) is in working order. Apparatus and Material Required Principle Diode: A diode is a two-terminal semiconductor device that allows current to flow in only one…
Lateral Deviation of a Light Beam Aim To observe refraction and lateral deviation of a beam of light incident obliquely on a glass slab. Apparatus and Material Required Principle A ray of light incident on a rectangular glass slab bends at the interface of two optical media, here, air and the glass. The emerging ray out…
Aim To study the variation in potential drop with length of a wire for a steady current. Apparatus and Material Required Principle If a steady current is flowing through a wire with uniform cross section and constant resistance per unit length, potential drop \(V\) across two points of the wire is directly proportional to the length…
