Consider the following two statements:
Statement I: | Kirchhoff’s junction law follows from the conservation of charge. |
Statement II: | Kirchhoff’s loop law follows from the conservative nature of the electric field. |
1. | Both Statement I and Statement II are correct. |
2. | Statement I is correct but Statement II is incorrect. |
3. | Statement I is incorrect but Statement II is correct. |
4. | Both Statement I and Statement II are incorrect. |
(a) | conservation of the current density vector. |
(b) | conservation of charge. |
(c) | the fact that the momentum with which a charged particle approaches a junction is unchanged (as a vector) as the charged particle leaves the junction. |
(d) | the fact that there is no accumulation of charges at a junction. |
Which of the above statements are correct?
1. | (b) and (c) |
2. | (a) and (c) |
