The resistance of a conductor is proportional to its length and inverse proportional to its cross-sectional area. So, If the fuse wires are thick, the larger cross section decreases the […]
It is very much advisable to use alloys in place of pure metals that have low melting point. Note: The most commonly used fuse wire is made of alloy consisting […]
A fuse wire is made of tin alloy because it has low melting point, so that it may melt easily, whereas a copper wire cannot be used as a fuse […]
A copper wire cannot be used as a fuse wire because it has a high melting point. It will not melt easily when a high electric current passes through it […]
Electrical contacts are generally made from metals with high electrical conductivity, except in applications such as high-power equipment brushes where abrasive wear is expected. The most commonly used metal surfaces […]
Copper has a higher melting point than the tin used in fuse wire. So, when a high level of current runs through copper wire, it continues to heat but will […]
Copper is better at heat transfer and aluminum is better at heat dissipation, so good heat-sinks have a copper base that quickly/efficiently gets the heat away from whatever is being […]
Answer. Copper and aluminium are good conductors of electricity. They have very low resistance and allow the current to flow through them easily. Hence, they are used to make wires […]
Copper is used in normal wiring due to its high melting point. Copper with a higher melting point won't melt easily when there is a current overload and thus allow […]
Copper has a higher melting point than the tin used in fuse wire. So, when a high level of current runs through copper wire, it continues to heat but will […]
