However, unlike an ammeter, you must connect the voltmeter in parallel to measure the potential difference across a component in a circuit.

In circuits connected in parallel, the components are connected on different branches. Find out more with BBC Bitesize. For students between the ages of 11 and 14.

With S 2 in the lower position, both LED drivers connect in parallel, and the tested zener voltage is approximately 20 to 25V at several milliamps of current. Both parallel and in-series connections ...

The circuit in Figure 1 measures both the true-rms value and the rectified average value of an ac signal. This design uses two low-cost ICs in SOIC packages and consumes only 180 µA of quiescent ...
