Rubber.
Leather is not a good conductor of electricity. It is an insulator, meaning it does not allow electricity to flow through it easily.
Insulators, such as wool, styrofoam, or air, do not allow heat to pass through easily because they have low thermal conductivity. This property makes them useful for keeping things warm or cool.
Insulators - they cannot allow electricity to flow through them as they have no mobile charge carriers present. Insulators - they cannot allow electricity to flow through them as they have no mobile charge carriers present.

Conductivity is the measure of a material's ability to conduct electricity. It indicates how easily electric currents can flow through a substance. Materials with high conductivity allow electricity to flow through them easily, while materials with low conductivity resist the flow of electricity.
An opaque substance does not allow light to pass through it. Examples include wood, metal, and thick plastics.
rubber would be an example of something that does not allow electricity to move through it easily
Mud is neither transparent nor translucent. Mud is an opaque substance, meaning that it does not allow light to pass through it easily. As a result, you cannot see clearly through mud.
metal
The value of a fuse shows how many volts of electicity it will allow to pass through until it cuts out. For example a fuse saying 5A will allow anything up to 5A to pass through but if any more than that flows into it, the fuse will cut out.

A marker is typically made of plastic, which is an insulator. Insulators do not allow electricity to flow through them easily, whereas conductors allow electricity to flow through them easily.
