Which of the following is the correct set-up of a circuit?
An ammeter is used to measure the electric current in a circuit and voltmeter is used to measure the voltage. A voltmeter is connected in parallel with a device to measure its voltage, while an ammeter is connected in series with a device to measure its current.
The positive terminal of an ammeter should be connected to the positive terminal of the battery and the positive terminal of a voltmeter should be connected to the positive terminal of the battery.
