A `9000 Omega` voltmeter is connected across a resistor R and an ammeter of ressistance `0.015 Omega` in series. The voltmeter reads 117V and a ammeter reads 0.13A. Calculate the value of R and power input to R.

If resistance of voltmeter is 10000 Omega and resistance of ammeter is 2Omega then find R when voltmeter reads 12 V and ammeter reads 0.1 A

A battery of emf 3V and internal resistance r is connected in series with a resistor of 55 Omega through an ammeter of resistance 1 Omega . The ammeter reads 50 mA. Draw the circuit diagram and calculate the value of r.

A students connects an ammeter A and a voltmeter V to measure a resistancer as shown in figure. If the voltmeter reads 20 V and the ammeter reads 4A , then R is
