The source of displacement current is __________ .
- A Changing Electric field
- B Static Electric field
- C Changing Magnetic field
- D Static Magnetic field
Answer & Solution
Correct Answer
(A) Changing Electric field
Step-by-step Solution
Detailed explanation
(Α) Changing Electric field
\(i_{d}=\varepsilon_{0} \frac{d}{d t}\left(\phi_{\mathrm{E}}\right)\)
\(i_{d}=\varepsilon_{0} \mathrm{~A} \frac{d}{d t}(\mathrm{E}(t))\)
\(i_{d}=\varepsilon_{0} \frac{d}{d t}\left(\phi_{\mathrm{E}}\right)\)
\(i_{d}=\varepsilon_{0} \mathrm{~A} \frac{d}{d t}(\mathrm{E}(t))\)
