In the circuit shown the resistance of voltmeter is 10000 ohm and that of ammeter is 20 ohm . The ammeter reading is 0.10 amp and voltmeter reading is 12 volts. Then R is equal to

The voltmeter V in the figure. Reads 117V and the ammeter A reads 0*13A . The resistance of the voltmeter is 9000Omega and the resistance of ammeter is 0*015Omega . Compute (i) the resistance R, (ii) the power input to R.

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

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.

Resistance value of an unknown resistor is calculated using the formula R=V/I where V and I be the readings of the voltmeter and the ammeter respectively. Consider the circuits below. The internal resistances of the voltmeter and the ammeter ( R_v and R_G respectively ) are finite and non zero. Let R_v and R_G be the calculated values in the two cases A and B respectively. If the resistance of voltmeter is R_v=1kOmega and that of ammeter is R_G=1Omega the magnitude of the percentage error in the measurement of R (the value of R is nearly 10Omega ) is:

A student connects a voltmeters, ammeter and resistance according to the circuit given. If the voltmeter reading is 20V and ammeter reading is 4A, then the resistance will be

A cardidate connects a moving coil voltmeter V , a moving coil ammeter A and a resistance R as shown in figure. If the voltmeter reads 24 V and the ammeter reads 4 A , R is
