Q. |
A Fuse wire is characterized by – |
A. | High resistance and low melting point |
B. | High resistance and high melting point |
C. | Low resistance and high melting point |
D. | Low resistance and low melting point |
Answer» D. Low resistance and low melting point | |
Explanation: A fuse is a type of low resistance resistor that acts as a sacrificial device to provide over current protection, of either the load or source circuit. Low resistance causes the fusewire to melt if a current more than the safe current for the appliance starts flowing through the circuit. |
