Question

what precaution to take while conducting experiment to test electric conductive of liquids

Answer 1

Current: The movement of electrical charge measured in ampere (amps).
Voltage: Measure of electrical force or potential difference in volts.
Watt: Unit of electric power, equals the voltage multiplied by current (W=V x A).
Resistance: Opposition to current flow measured in ohms.
Conductors: Materials that have little resistance to electricity.
Insulators: Materials that have high resistance to electricity.
Grounding: A conductive connection to the earth serving as a sink for the current that is used as a protective measure against static electricity build-up.
