When an ammeter of negligible internal resistance is inserted in series with circuit, it reads `1 A`. When a voltmeter of very large resistance is connected across `R_(1)`, it reads `3 V`. But when the points `A` and `B` are short-circuited by a conducting wire, then the voltmetre measures `10.5 V` across the battery. The internal resistance of the battery is equal to img src="https://d10lpgp6xz60nq.cloudfront.net/physics_images/BMS_V03_C06_E01_051_Q01.png" width="80%"
