STANDARD Physics Resistors MCQ Question
Type: MCQ-conceptual-Medium-Class 12
Wire bound resistors are made by
A
winding the wires of an alloy viz, Cu, Al, Ag
B
winding the wires of an alloy viz, Si, Tu, Fe
C
winding the wires of an alloy viz, Ge, Au, Gr
D
winding the wires of an alloy viz, manganin, constantan, nichrome.
Correct Answer
Option D
Detailed Explanation
Wire bound resistors are made by winding the wires of an alloy, viz. manganin, constantan, nichrome etc. The choice of these materials is dictated mostly by the fact that their resistivities are relatively insensitive to temperature. These resistances are typically in range of a fraction of an ohm to a few hundred ohms.
