Does the safe current of a fuse wire depend on the length of the wire?

Does the current depend on the length of the conductor?

Does the current depend on the area of cross- section of the wire used.?

The breaking stress of a wire depends upon

The length of a metallic wire is L_1 : when tension on the wie is T_1 , and length is L_2 , when the tension in the wire is T_2 , Find original length of the wire.

A conducting loop is held below a current carrying wire PQ. Predict the direction of the induced current in the loop, when the current in the wire is constantly increasing.

A long straight wire carrying current of 25 A rests on a table as shown in Fig. EP 4.22. Another wire PQ of length 1m, mass 2.5 g carries the same current but in the opposite direction. The wire PQ is free to slide up and down. To what height will PQ rise?

Does one part of a wire carrying curent exert a force on another part of the same wire?

Two parallel wires in free spaces are 10cm apart and each carries a current of 10A in the same direction. The force one wire exerts on the other per metre of length is
