If a man has five resistors each of value $$\dfrac { 1 }{ 5 } \Omega $$ then is the maximum resistance he can obtain  by connecting them, is :

Conventionally, the direction of the current is taken as the direction of flow

Three fuse wires A, B and C tinned copper having identical cross section and length 8 cm, 12 cm and 16 cm are used as fuses. For the same value of current 

An electric heater kept in a vacuum is heated continuously by passing an electric current. Its temperature:

A uniform wire of resistance $$50\Omega$$ is cut into 5 equal parts. These parts are now connected in parallel. The equivalent resistance of the combination is

Three resistors each of $$10 \Omega$$ are connected in series to a battery of potential difference 150 v. The current flowing through it is ..... A.
