Answer:
Source of current, force and pathway.
Explanation:
Source of current, force and pathway are the three important things needed or responsible for the current flow. A supply of electric charges (electrons) which is provided by the electric source, force of push to move the charges through the circuit and a pathway on which current flows. Without these three things, flow of current is impossible. so we can say that the situation in which all these three things are present will allow the current to flow in the circuit.

Production of energy using water power
Using electricity or energy-saving products, creation of technology to capture sulfur dioxide are the processes that can be taken into account.
<h3><u>Explanation</u>:</h3>
Acid rain is a very serious issue in the urban areas now a days. Acid rain forms due to the excessive production of gases like sulphur dioxide, nitrogen oxides etc which are beyond the level of absorption by the environment. This gases go up in the atmosphere and they mixes with cloud water to form corresponding sulphuric acid and nitric acid. These acids come along the rain and decrease the pH of the water bodies as well as soil.
If we start using water as the source of our energy production, then we can eliminate the use of coal and other fossil fuels which are chief sources of these gases.
If we can grow some technology to capture these gases before they are released into the environment, then also there will be less problems. Technologies like alkali bath are not so operative in large scales.
We can use electricity in boilers and other places where still, fossil fuels are brunt to produce the heat so that sulphur oxides don't come out.
