Note: Mark a ( ) in appropriate column.
Result
The circuit connected as per the corrected circuit diagram is functional.
Precautions
1. Before making connections, clean the ends of the connecting wires with the help of sand paper.
2. Always connect the voltmeter in parallel with the resistor and ammeter in series with the resistor.
3. The positive terminal of the battery should be connected to the positive terminals of the voltmeter and
