Answer Posted / parth
the correct answer would be (d) mass.
see, when you put a hot iron rod in water, it will transfer
its heat to the water and cool down, without providing any
voltage, current or doing any work on it. the only thing
required is a sufficient amount of water. so sufficient
Mass of water is required.

L.A. (Lightening Arrester) is located at a place from where transmission line enters the transmitting substation. So L.A. (Lightening Arrester) is the first equipments which has to encounter with lightening, high voltage surges and switching surges. It has to absorb energy of lightening, high voltage surges, and switching surges. L.A. (Lightening Arrester) is made up of layers of semiconductors. If these layers can not tolerate energy released by lightening, high voltage surges, and switching surges the L.A. (Lightening Arrester) blasts.
