Ohmeters are placed in _____ with the circuit to measure resistance.

Ohmeters are specifically designed to measure resistance, and they must be connected in parallel with the circuit. This configuration allows the ohmeter to measure the resistance of the component or section of the circuit without impacting the operational current of the circuit itself. When placed in parallel, the ohmeter can provide a direct reading of resistance because it effectively takes a small sample of the voltage, providing an accurate representation of resistance across the component without altering the circuit’s functionality.

If an ohmeter were placed in series, it would introduce its own resistance into the circuit and disrupt the flow of current, yielding inaccurate readings or potentially damaging the meter or the circuit. Thus, the necessity for parallel connection ensures accurate resistance measurement while maintaining circuit integrity.
