Two wires A and B of same metal are connected in parallel. Wire A has length $$l$$ and radius $$r$$ and wire B has length $$2l$$ and radius $$2r$$. then the ratio of total resistance of parallel combination and the resistance of wire A is

Five resistances of R $$\Omega$$ were taken. First three resistances are connected in parallel combination and rest two are connected in series combination, then the equivalent resistance is :

1μA =________  mA1μA =________  m

The resistance of one conducting wire is $$10 $$. How much electric current will flow by connecting it with a battery of $$1.5 V$$ ?

If the five equal pieces of a resistance wire having $$5 $$ resistance each is connected in parallel, then their equivalent resistance will be

Materials which allow current to pass through them easily are called?

The amperage of the fuse wire used in a circuit that works on $$230 \ V$$ is $$2.2 \ A$$. If so. the power of the device is

If $$500\Omega$$ of resistance is made by adding five $$100\Omega$$ resistance of tolerance $$4\%$$, then the tolerance of the combination is .

Answer the question:
Two $$5.0\Omega$$ resistors are connected as shown in the diagram.
What is the total resistance of the combination ?

In which direction conventional current flow in an electric circuit:
