A multimeter is a device that is connected in which manner?

A multimeter is designed to be connected in a high impedance, parallel configuration when measuring voltage. The high impedance characteristic of the multimeter allows it to draw minimal current from the circuit being tested, thus preventing any significant alteration of the circuit's behavior. This ensures that the voltage measurement accurately reflects the voltage present in the circuit without loading it down or affecting its operation.

When measuring resistance, a multimeter generates a small test current and measures the voltage drop across the resistor to calculate resistance, but this is separate from the measurement of voltage. Thus, in its primary roles, the multimeter's high impedance setting minimizes the disruption of the normal operation of the circuit or component under test.

In contrast, if a multimeter were connected in a low impedance manner, either in series or parallel, it would draw more current than necessary, which could lead to inaccurate readings or damage to the multimeter and the circuit under test. Therefore, the correct configuration for connecting a multimeter for voltage measurement is high impedance in parallel.
