If electric potential is constant in a region, electric field in that region is:
If electric potential is constant in a region, electric field in that region is:
Show Hint
No change in potential means no electric field.
Updated On: Jun 6, 2026
- finite and constant
- zero
- infinite
- varying
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Concept
Relation between Electric Field ($E$) and Potential ($V$): $E = -dV/dx$.
Step 2: Meaning
If potential is constant, its derivative is zero.
Step 3: Analysis
Since potential is constant ($dV=0$), the electric field $E$ must be zero.
Step 4: Conclusion
The electric field is zero.
Final Answer: (B)
