Five `4 Omega` resistances, a 2 V battery and an ammeter are connected s shown in Fig. 4.43. Find the ammeter reading.

Five 4 Omega resistance, 2 V battery and an ammeter are connected as shown in figure. Find the ammeter reading.

An ammeter A is connected as shown in the diagram. Ammeter reading is

An ideal ammeter (zero resistance) and an idel voltmeter (infinite resistance) are connect as shows in Fig. 6.47 . The ammeter and the voltmeter readings are

An ammeter A, a voltmeter V and a resistance R are connected as shown in the figure. If the voltmeter reading is 1.6V and the ammeter reading is 0.4 A, then R is

ABCDFPA is a network of three batteries of the e.m.f's E, 12 V and 4 V respectively and three resistance 2Omega,4Omega and 6Omega connected as shown in the diagram. An ideal ammeter connected between F and P shows a current reading of 0.5 A. Then the value of the e.m.f. E is

A cell has an emf of 3 volt and internal resistance 2Omega . It is connected to an ammeter having resistance 2Omega and to an external resistance of 100Omega . When a voltmeter is connected across the 100Omega . Resistance, the ammeter reading is 40 mA. The resistance of the voltmeter is

A galvanometer (coil resistance 99 Omega .) is converted into an ammeter using a shunt of 1 Omega and connected as shown in figure (a). The ammeter reads 3 A . The same galvanometer is convened into a voltmeter by connecting a resistance of 101 Omega in series. This voltmeter is connected at, shown in figure (b). Its reading is found to be 4/5 of the full scale reading. Find : (a) internal resistance r of the cell (b) range of the ammeter and voltmeter (c) full scale deflection current of the galvanometer.
