When a battery voltage is measured by placing a high-resistance voltmeter across the terminals of the battery, the voltmeter reads 6.3V. With the voltmeter leads still attached, the battery terminals are then connected to a resistor in series with an ammeter. In this arrangement, the ammeter reads 150 mA, and the voltmeter reads 5.9V. What are the emf and the internal resistance of the battery?
For the circuit shown in the figure, both meters are idealized, the battery has no appreciable internal resistance, and the ammeter reads 1.45 A.
