$A$ 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:

Two wires of the same material and equal length are joined in parallel combination. If one of them has half the thickness of the other and the thinner wire has a resistance of $8\, \Omega$,the resistance of the combination is equal to

Four identical bulbs,each rated $100 \, W, 220 \, V$,are connected across a battery as shown. The total electric power consumed by the bulbs is.......$W$.

Three unequal resistors in parallel are equivalent to a resistance of $1 \ \Omega$. If two of them are in the ratio $1:2$ and if no resistance value is fractional,then the largest of the three resistances in ohms is

The equivalent resistance between the terminals $A$ and $B$ is ............. $\Omega$.

Find the effective resistance between $A$ and $B$ in the given circuit.
