The plastic covering that surrounds wires is an electrical insulator.

Solids with Schottky defects are electrical insulators.

Conductors and insulators

Identify the type of cyrstalline solid based on the following properties : (a) Conducts electricity in the molten state but in the solid state. (b) Very hard with melting point and acts as electrical insulator. (c) Conducts electricity in the solid state, malleable and ductile.

A circular insulated copper wire loop is twisted to form two loops of are A and 2A as shown in the figure. At the point of crossing the wires remain electrically insulated from each other. The entire loop lies in the plane ( of the paper). A uniform magnetic vecB point into the plane of the paper . At t=0, the loop starts rotation about the common diameter as axis with a constant angular velocity omega in the magnetic field. Which of the following options is /are correct ?

Why is it not advisable to use a piece of copper wire as fuse wire in an electric circuit ?

Three infinite current carrying conductors are placed as shown in Fig. Two wires carry same current while current in third wire is unknown. The three wires are electrically insulated from each other and all of them are in the plane of paper. Which of the following is correct about point P which is also in the same plane?
