The constriction causes the mercury column to break under tension, leaving a vacuum between the bottom of the column and that in the bulb, and the top of the column stays still at the position reached in the body - a "peak hold" system.
The spinning turbine converts mechanical energy into electrical energy that is converted into light energy used to light up the house.
<h3>What is law conservation of energy?</h3>
The law of conservation of energy states that energy can neither be created nor destroyed but can be transformed from one form to another.
The spinning turbine works on the principle of mechanical energy.
Thus, the spinning turbine converts mechanical energy into electrical energy that is converted into light energy used to light up the house.
