Figure 3. A single battery and a single resistor are connected together with meters as follows. The bottom, negative side, of the battery connects to the bottom end of the resistor. The top, positive side, of the battery connects to the positive side of an ammeter. The negative end of the ammeter connects to the top end of the resistor. The negative end of a voltmeter connects to the bottom end of the resistor. The positive end of the voltmeter connects to the top of the resistor.
