Redrawing the circuit diagram with marking of current and voltage

From the circuit diagram
`i_(g) R_(1) = V_(BB) - V_(ee)`
if `R_(1) ` is increased `i_(B)` will decrease
`So ` if `i_(B)` decreased `I_(C)` is also decreased So there is a decrease in ammeter and voltmeter readings.

If the resistance R_(1) is increased (see figure), how will the reading of the ammeter and voltmeter change ?

In the circuit shown, the reading of the voltmeter and the ammeter are

If by mistake Ammeter is connected parallel to the resistance then i-V curve expected is (Here i = reading of ammeter, V= reading of voltmeter)

An ammeter and a voltmeter are initially connected in series to a battery of zero internal resistance. When switch S_(1) is closed the reading of the voltmeter becomes half of the initial, whereas the reading of the ammeter becomes double. If now switch S_(2) is also closed, then reading of ammeter becomes :

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

In the given circuit the readings of the voltmeter V_(1) and the ammeter A are .

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.

The ammeter A reads 2A and the voltmeter V reads 20V, the value of resistance R is (Assuming finite resistance's of ammeter and voltmeter)

An ammeter of zero resistance and a volt meter are connected in series to a battery of emf 6.0 volt and certain internal resistance. When a resistance R is connected in parallel with the voltmeter the readings of the voltmeter becomes half of its initial reading and the reading of the ammeter becomes 2 times to its initial reading (before R is connected). Find the voltmeter reading in volt after the connection of the resistance.
