The resistors `R_(1),R_(2),R_(3)` and `R_(4)` in the figure given below are all equal in value.

What would you expect the voltmeters A,B and C to read assuming that the connecting wires in the circuit have negligible resistance ?

For three circuits, shown here the same two resistors R_(1) and R_(2) have been connected in parallel in all the circuits but the voltmeter and the ammeter have been connected in three different positions. The relation between the three voltmeter and ammeter readings would be :

5 resistances R_(1), R_(2),R_(3),R_(4),R_(5) are joined as shown in the figure. The values of R_(1), R_(2), R_(3) and R_(4) are so adjusted that the current in the circuit does not change for any value of the resistance R_(5) . This is possible for the following relation

In the circuit shown below, the ammeter A reads 5 A and the voltmeter V reads 20 V The correct value of resistance R is

The ammeter, voltmeter and, resistors R_(1) and R_(2) connected in the circuit as shown below have been checked and found to be correct. On plugging the key, the voltmeter reads 4.5 V but the ammeter reads 1.5 A. This is most likely because the wires joined to :

In the circuit diagram given below, three resistors R_(1),R_(2) , and R_(3) of 5 Omega, 10 Omega and 30 Omega , respectively are connected as shown. Calculate: (a) current through each resistor. (b) total current in the circuit. (c) total resistance in the circuit.

The power dissipated in resistor R_(3) shown in the figure is 15 W. The reading the ammeter is 500 mA and the reading of the voltmeter is 10 V. Ammeter, voltmeter and battery are ideal. Find the resistance R_(1)

The power dissipated in resistor R_(3) shown in the figure is 15 W. The reading the ammeter is 500 mA and the reading of the voltmeter is 10 V. Ammeter, voltmeter and battery are ideal. Find the resistance R_(3)

In the circuit shown below, if the value of R is increased then what will be the effect on the reading of ammeter if the internal resistance of cell is negligible-

To find the value of resistance R using Ohm's law, we are given four voltmeters as below. Which one will you prefer to be connected in the circuit?
