$A$ wire of resistance $R$ and length $L$ is cut into $5$ equal parts. If these parts are joined in parallel,then the resultant resistance will be:

The effective resistance between $A$ and $B$ in the figure is $\frac{7}{12} \Omega$ if each side of the cube has $1 \Omega$ resistance. The effective resistance between the same two points,when the link $A B$ is removed,is

What is the equivalent resistance between points $A$ and $B$ in the given circuit?

An electric kettle has two coils. When one of these is switched on,the water in the kettle boils in $6\,min$. When the other coil is switched on,the water boils in $3\,min$. If the two coils are connected in series,the time taken to boil the water in the kettle is ............. $min$.

By which of the following single load resistance should the load bridge be replaced so that the power to the load remains unchanged (in $Omega$)? (Given $r = 3 \ \Omega$ for each resistor in the bridge)

Calculate the equivalent resistance across $A-B$ in the given circuit. ............... $\Omega$
