measure resistance with a multimeter in a circuit is the power going to be off or on

i think ON

To measure resistance with a multimeter, the circuit must be powered off. The reason for this is that when the circuit is powered on, the current flowing through it can interfere with the resistance measurement. The multimeter itself applies a small voltage to the circuit and measures the resulting current to determine the resistance. If the circuit is powered on, the current from the power source can influence these measurements and give inaccurate results. Therefore, it is important to always turn off the power before measuring resistance with a multimeter.
