Answer 1

The Ohmmeter itself has a voltage supply.

Answer 2

Resistance measurement requires the circuit to be isolated from any external voltage sources. An ohmmeter provides its own voltage to measure resistance by passing a small current through the component and measuring the voltage drop. If there is an additional voltage in the circuit, it can interfere with the ohmmeter’s readings, potentially giving inaccurate results or damaging the meter. Thus, the voltage in the circuit must be zero to ensure a correct and safe resistance measurement.
