Due to this, the surrounded area of the conductor gets warmed up.

To avoid this ohmic loss, electricity must be transmitted at a high voltage.

The excess heat produced can cause a fire burst by damaging the insulation and other components.

The heat sinks used as coolants can add an extra cost.

The heating effect of current reduces the lifetime of some components in the electric circuit.

An electric furnace needs more time to heat up and warm the surrounding, which results in slower heating.

Due to slower heating, electricity is used in the long run, which is highly expensive.
