How a voltmeter is connected in a circuit
WebSince an ammeter has very little resistance, it will act as a short circuit if placed in parallel (across the terminals of) a substantial voltage source. If this is done, a surge in current will result, as shown in Figure 2, potentially damaging the meter. Figure 2. Ammeter short circuit connection resulting in a surge current. WebA voltmeter is a device or instrument that measures the amount of voltage throughout a circuit. Voltmeter is connected parallel with the circuit to measure its voltage. We …
