Assertion(A): A cell converts chemical energy into electrical energy.
Reason(R): A cell maintains a potential difference across its terminals due to chemical reactions.
Choose the correct option:
i. Both A and R are true and R is the correct explanation of A.
ii. Both A and R are true and R is NOT the correct explanation of A.
iii. A is true and R is false.
iv. A is false and R is true.
( Please answer only if you are absolutely sure about it )
Answers
Answer:yes the option 1 is correct assertion and reason both are true
Explanation:as due to the potential difference current is flowing continuously and thi potential difference is maintained by cell
Let us look at the answer:
Both A and R are true and R is correct explanation of A .
Explanation:
A cell is a device which converts chemical energy into electrical energy. There are two types of cells, primary and secondary cells.
primary cells are used in remotes. The chemicals used in it are converted into electrical energy. They are used until the whole chemical in the insulated box is used up.
secondary cells are used in car batteries. The chemicals used in it can recharged from time to time.
The cell maintains potential difference across its end to regulate the flow of current. so that the reaction is completed efficiently.
