Dear Anurodh The question Which of these is not a useful precaution in an electrical experiment? key should be removed between readings to avoid battery run-down jockeys should be dragged on resistance wires So if we talk about something useful precautions for electrical experiment is not useful options are: jockeys should be dragged on resistance wires readings should be recorded as soon as they are obtained
The Jockeys should NOT be dragged in resistance wire as they can change the physical structure of the wire
