Precautions
The connecting wires used should be thick copper wire and using sandpaper, the insulation at the end of the wires should be removed.
The connections should be tight to avoid introducing external resistance.
To make connections, the circuit diagram should be referred to.
To make the current entry from the positive terminal and exit from the negative terminal, the ammeter should be connected in series.
Resistor and voltmeter should be connected in parallel.
The least count of ammeter and voltmeter should be calculated properly.
When there is no current flow, the ammeter and voltmeter should be at zero.
To avoid heating and change the resistor’s resistance value, the current should flow while taking the readings.
Please mark as the brainliest.
