COMEDK · Physics · 18. Capacitance
When a dielectric slab of dielectric constant \(\mathrm{k}=2\) is used to fill the space between the plates of a parallel plate capacitor, the capacitance of the capacitor is found to be \(20 \mu \mathrm{F}\). What will be the capacitance when the slab is replaced with air?
- A \(40 \mu F\)
- B \(20 \mu F\)
- C \(5 \mu F\)
- D \(10 \mu F\)
Answer & Solution
Correct Answer
(D) \(10 \mu F\)
Step-by-step Solution
Detailed explanation
The capacitance of a parallel plate capacitor filled with a dielectric material is given by the formula \(C = K C_0\), where \(C\) is the capacitance with the dielectric, \(K\) is the dielectric constant, and \(C_0\) is the capacitance with air as the medium. Given…
