All the description given are correct.
Step-by-step explanation:
- The electronic components like a switch, cell, battery, resistor, variable resistor, lamp, fuse, voltmeter, ammeter, photoresistor, etc are given in be the box.
- The electronic components are inevitable for a circuit to function hence knowing their function is also very important. The description for all of these are correct and to the point.
- To add more to the description of fuse and photoresistor, the fuse is something which is used in the circuit to cut down the current if there is a short circuit. A photoresistor is sensitive to lights. It works with the presence of light.
