question

If the conductivity and relative permittivity of a medium are 0.3 mho/meter and 60 respectively, assuming that\mu_r= 1, does the medium behave like a conductor or a dielectric at a frequency of: (a) 100 KHz, (b) 3000MHz?

category

engineering

options

  1. At 100 KHz, its behavior is frequency-independent. At 3000MHz, it behaves like a dielectric.
  2. At both frequencies, its behavior is frequency-independent, acting neither as a good conductor nor as a dielectric.
  3. At both frequencies, it behaves like a dielectric.
  4. At 100 KHz, it behaves like a conductor with high losses. At 3000MHz, its behavior is frequency-independent.
  5. At 100 KHz, it behaves like a poor conductor. At 3000MHz, it behaves like a dielectric with high losses.
  6. At 100 KHz, it behaves like a dielectric. At 3000MHz, it behaves like a conductor.
  7. At 100 KHz, it behaves like a good conductor. At 3000MHz, it behaves like a dielectric.
  8. At 100 KHz, it behaves like a dielectric with high losses. At 3000MHz, it behaves like a good conductor.
  9. At 100 KHz, it behaves like a dielectric. At 3000MHz, it behaves like a good conductor.
  10. At both frequencies, it behaves like a good conductor.
