Those are the three ways that heat can move
from one place to another.
There aren't any other ways.
The answer is modulation. In modulation a radio wave (also called the "carrier signal") is changed by the signal we want to send to the receiver, for example a song, or, in a wireless network, some data from a computer.
In order to reduce the amount of energy lost due to heat flow, electricity is delivered to our homes using <u>d. low current</u>.
<u>Explanation</u>:
The presence of flow of electrons is said to be electricity. The electricity flows in one direction. The electricity enables function of the electrical devices and machines.
Heat is generated when the electricity flows from one place to another. So the energy is lost in the form of heat.
So to avoid the loss of energy, the electricity is delivered to home using low current. The strength of an electric current can be measured and represented in the unit of ampere.
