Consider the following statements with reference to the equation δp δt
1. This is a point form of the continuity equation
2. Divergence of current density is equal to the decrease of charge per unit volume per unit at every point
3. This is Max well's divergence equation
4. This represents the conservation of charge Select the correct answer:
-
- Only 2 and 4 are true
- 1, 2 and 3 are true
- 2, 3 and 4 are true
- 1, 2 and 4 are true
Correct Option: D
| ∇ .J = | ||
| δt |
This a point form of continuity equation because divergence is a point fundamental property. This represents conservation of the charge. And divergence of current density is equal to decrease of charge per unit volume per unit at every point.
