WebDec 12, 2024 · 1. Connect the ammeter leads to the circuit. This process will depend on your model of ammeter. Essentially, the negative ( - ) end of your ammeter will connect to the power source side of the broken circuit. The positive end (+) will connect to the opposite side, so that the ammeter bridges the break. WebIn Figure 18.8, the current is measured with the ammeter on the right side of the circuit diagram. When the switch is closed, does the reading on the ammeter (a) increase, (b) decrease, or (c) remain the same? Figure 18.8 (Quick Quizzes 18.5 and 18.6)

WebAnswer (1 of 5): Analog meters have moving coils with a relatively low internal impedance which varies with the voltage range selected on the meter. e.g. a 10kOhms/Volt sensitivity meter on the 10V range will give a 100kOhm load to whatever you are measuring. A digital meter will have an input bu... WebDrag the wire and place it on the voltmeter to have it connected. Once all connections are made, click and drag the key to insert it into the switch. Slowly move the rheostat contact to change the volt and current in the Voltmeter and Ammeter accordingly. The readings are shown both in Voltmeter and Ammeter and also as readings on the left side ...
