Question:
Which of the following statements is true about the voltaic cell?
Which of the following statements is true about the voltaic cell?
Show Hint
A voltaic cell makes electricity from a spontaneous chemical reaction.
Updated On: Oct 1, 2026
- It converts chemical energy into electrical energy.
- It converts electrical energy into chemical energy.
- The anode of voltaic cells is positive.
- The cathode of voltaic cell is negative.
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Recall the idea
A voltaic (galvanic) cell uses a spontaneous redox reaction to produce an electric current. Chemical energy turns into electrical energy.
Step 2: Check the options
(A) is true.
(B) describes an electrolytic cell, so it is false.
(C) In a voltaic cell the anode is the negative electrode (oxidation releases electrons), so it is false.
(D) The cathode is positive in a voltaic cell, so it is false.
Final Answer:
A voltaic cell converts chemical energy to electrical energy, option (A). \[ \boxed{\text{(A)}} \]
