The figure given below shows three resistors

Their combined resistance is:

Explain with the help of a labelled circuit diagram, how you will find the resistance of a combination of three resistors of resistances R₁, R₂ and R₃ joined in parallel.

In the diagram shown below, the cell and the ammeter both have negligible resistance. The resistors are identical

With the switch K open, the ammeter reads 0.6 A. What will the ammeter reading when the switch is closed?

If two resistors of 35 Ω and 15 Ω are joined together in series and then placed in parallel with a 40 Ω resistor, the effective resistance of the combination is :

The diagram below shows part of a circuit:

If this arrangement of three resistors was to be placed by a single resistor, its resistance should be :
