When the point A and B are shorted by a conducting wire, the voltmeter measures 10 V across the battery. The internal resistance of the battery is equal to

When an ammeter of negligible internal resistance is inserted in series with circuit it reads 1A When the voltmeter of very large resistance is connected across X it reads 1V. When the point A and B are shorted by a conducting wire, the voltmeter measures 10 V across the battery. The internal resistance of the battery is equal to

In the given circuit the reading of ideal voltmeter is E/2. The internal resistance of the battery is
