Power should be removed from the circuit before measuring resistance, and this statement is true. When measuring resistance, it is crucial to ensure that there is no voltage present in the circuit. This is because a live circuit can lead to inaccurate resistance readings due to the influence of current flow. Additionally, attempting to measure resistance while power is applied can potentially damage the multimeter or the circuit itself, as the device is not designed to handle voltage when measuring resistance. Therefore, de-energizing the circuit is a standard safety procedure that ensures accurate measurements and protects both the measuring instrument and the circuit components.
