As we learn

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

* If the item has four or more terminals and is in the form of chip then it is an IC ( Integrated Chip)

* If the item has three terminals it is a transistor

* If it has two items it may be a diode, LED, a resistor or capacitor

* Look for colour band. If it is a set of three colours it is a resistor

* If multimeter shows an equal deflection in both the directions the component is a resistor  

 

 

- wherein

* If multimeter does not show any deflection the component is a diode

* If multimeter shows less deflection in other direction it is LED

* If it does not show any deflection on connecting terminals in either way, it is a capacitor

Result:

A diode, an LED, IC, resistor or capacitor can be identified. 

 

 Correct option is 1
