it contains ,, different appliances ,

1. resistors ( bulbs)

2. key

3, battery

4. wire . ( which circuit is made of )

5. ammeters ( for measuring current across the conductor/circuit )

6. voltmeter ( for measuring potential difference )

now ,, .

the device which helps in maintaining the potential difference is known as potentiometer.

hope it helps
