Hey Mate!!☺

----- Here's your answer -----

56)- Linear resistance obeys Ohm's Law as the voltage across the resistor islinearly proportional to the currentthrough it. Non-linear resistance, doesnot obey Ohm's Law but has a voltagedrop across it that is proportional to some power of the current. ... In other words the ease by which currentflows.

57)- An electronic component that is used to vary the amount of current that flows through a circuit. It works by sliding a wiper terminal across a resistive material, typically a thin film or chunk of carbon or a resistive wire made of nickel chromium or tungsten alloys.
