1.
A dielectric does not have leakage current.
Answer: Option
Explanation:
All dielectrics have some leakage current.
2.
A series RLC circuit has a resonant frequency of 1000 Hz. The maximum voltage across C is likely to occur at a frequency of about
Answer: Option
Explanation:
Maximum voltage across capacitance occurs at a frequency slightly less than resonant frequency.

5.
A network has two branches in parallel. One branch contains impedance Z1 and the other branch has impedance Z2. If it is fed from an ac voltage V of frequency f, the current through Z1 depends, on
Answer: Option
Explanation:
In parallel branches, the current through any branch depends only on voltage, impedance and frequency only.
