. Read the passage and answer the following questions. 3
Electric cell: A source is required to produce a uniform flow of charges in a circuit.
Such a general device is an electric cell. Various types of electric cells are available
today. These are used in a range of machines from wrist watches to submarines. Out
of these, you must be aware of solar cells. The main function of various electric cells
is to maintain a constant potential difference between its two terminals. The electric
cells work on the electric charges to maintain a constant potential difference.
1. Why do we need source in a circuit?
2. Where do we use cell in a day to day life?
3. Write the main function of electric cell.

The correct answer to the above questions are as follow -
1. We need a source in a circuit because the source produces a uniform flow of charges in a circuit. The source can be an electric cell, which produces a constant flow of current for the resistor to act. Current produces a potential difference between the circuit.
2. We use the cell in day-to-day life in wristwatches, and for operating modern technological devices. We use cells in a wide range of machines and in submarines.
3. The main function of the electric cell is to maintain a constant potential difference between its two terminals. This potential difference will cause the current to flow from a high potential to a low potential.
