Activities (For the purpose of demonstration only)

1.To identify a diode, an LED, a transistor, an IC, a resistor and a capacitor from amixed collection of such items.

2.Use of multimeter to (i) identify base of transistor, (ii) distinguish between npnand pnp type transistors,(iii) see the unidirectional flow of current in case of a diode and an LED, (iv) check whether a givenelectronic component (e.g., diode, transistor or IC) is in Working order.

3.To study effect of intensity of light (by varying distance of the source) on anLDR.

4.To observe refraction and lateral deviation of a beam of light incident obliquelyon a glass slab.

5.To observe polarization of light using two Polaroids.
