Choose the statement which is not correct in the case of an electric fuse.

Variation of current and voltage in a conductor has been shown in the diagram below. The resistance of the conductor is.

Two wires of the same material are given. The first wire is twice as long as the second and has twice the diameter of the second. The resistance of the first will be.

Two resistors of resistance $$R_{1}$$ and $$R_{2}$$ having $$R_{1} > R_{2}$$ are connected in parallel. For equivalent resistance $$R$$ , the correct statement is

If three resistors of resistance $$2\Omega, 4\Omega$$ and $$5 \Omega$$ are connected in parallel then the total resistance of the combination will be

Which of the following statement is false

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

$$10$$ wires (same length, same area, same material) are connected in parallel and each has $$1\Omega$$ resistance, then the equivalent resistance will be

A solenoid is at potential of difference $$60\ V$$ and current flows through it is $$15$$ ampere, then the resistance of coil will be 

When 25 A current with 10 ohm resistance flowing per second then the power lost in the cable during transmission is
