Are these Correct if not can you tell what is wrong? Thnx

All the description given are correct.

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.
