Question: What is the direction of the electric field in relation to the change in electric potential?
Option a: Electric field lines point in the direction of decreasing electric potential
- This is correct. The electric field E is defined as the negative gradient of the electric potential V: E = -∇V. This means E points in the direction in which V decreases most rapidly. Consequently......Login to view full explanation登录即可查看完整答案
